-- `ANTHROPIC_API_KEY` — required for generation
+## Running Locally — Claude Authentication
+
+The agent runtime uses `@anthropic-ai/claude-agent-sdk`. Two auth paths are supported:
+
+**Option A — API key (CI + production):**
+```bash
+# Add to .env at repo root (or export in your shell)
+ANTHROPIC_API_KEY=sk-ant-...
+```
+
+**Option B — Claude CLI login (local dev, one-time setup):**
+```bash
+# Install the Claude CLI if not already present, then:
+claude login
+# Follow the OAuth flow. Credentials are saved to ~/.claude/.credentials.json
+# No API key provisioning needed; the SDK picks up the session automatically.
+```
+
+API key takes precedence if both are set. `GET /api/health` returns `anthropic: 'ok'`
+for either path.
+
+## Other Environment Variables

 ## Section 9: Platform Dimensions Reference
 
-| Platform | Width (px) | Height (px) | Phase |
-|----------|------------|-------------|-------|
-| Instagram Square | 1080 | 1080 | 19 |
-| LinkedIn Landscape | 1200 | 627 | 21 |
-| One-Pager (US Letter) | 612 | 792 | 21 |
+| Platform | Width (px) | Height (px) | Phase | `schema.platform` value |
+|----------|------------|-------------|-------|------------------------|
+| Instagram Portrait (4:5) | 1080 | 1350 | 23 | `instagram-portrait` |
+| Instagram Square | 1080 | 1080 | 19 | `instagram-square` |
+| LinkedIn Landscape | 1200 | 627 | 21 | `linkedin-landscape` |
+| One-Pager (US Letter) | 612 | 792 | 21 | `one-pager` |
 
-**Phase 19 scope:** Instagram Square only (`1080 × 1080`). LinkedIn and One-Pager archetypes are Phase 21.
+**Phase 23 default:** Instagram Portrait (`1080 × 1350`) is the standard for all new archetypes. Instagram Square is legacy — only use on explicit request.
 
-All Phase 19 archetypes MUST use `"width": 1080, "height": 1080` in `schema.json` and `width: 1080px; height: 1080px` on `body` in `index.html`.
+New Phase 23 archetypes MUST use `"width": 1080, "height": 1350` in `schema.json`, `width: 1080px; height: 1350px` on `body` in `index.html`, and `"platform": "instagram-portrait"` as a top-level field.
+
+---
+
+## Section 10: Self-Documenting Metadata (Phase 23 — instagram-portrait archetypes)
+
+Phase 23 introduces a `meta` object in `schema.json` for all `instagram-portrait` archetypes. The `meta` object makes archetypes self-documenting so `list_archetypes()` can surface them with rich discovery signals without loading HTML.
+
+**This section is forward-only.** Existing archetypes (Phases 19–22) are unaffected and do not need to add `meta`.
+
+### Required `meta` fields (instagram-portrait only)
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `category` | `string` | Functional category for filtering (e.g., `"hero-photo"`, `"quote-testimonial"`) |
+| `imageRole` | `"none" \| "accent" \| "background" \| "hero" \| "grid"` | How image assets are used in the layout |
+| `useCases` | `string[]` (≥1) | Concrete scenarios where this archetype excels |
+| `slotCount` | `number` (integer, ≥1) | Total number of editable slots (text + image fields) |
+
+### Recommended `meta` fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `mood` | `string[]` | Descriptive mood tags (e.g., `["editorial", "bold"]`) |
+| `contentDensity` | `"sparse" \| "moderate" \| "dense"` | How much content the layout can hold |
+| `imageHints` | `object` | Guidance for selecting images from the DAM |
+| `avoidCases` | `string[]` | When NOT to use this archetype |
+
+### Full `meta` example
+
+```json
+{
+  "archetypeId": "photo-darken-headline",
+  "platform": "instagram-portrait",
+  "width": 1080,
+  "height": 1350,
+  "meta": {
+    "category": "hero-photo",
+    "mood": ["editorial", "cinematic", "bold"],
+    "contentDensity": "sparse",
+    "imageRole": "background",
+    "imageHints": {
+      "suggestedAspect": "4:5 or wider",
+      "suggestedSubject": "single person, landscape, or abstract texture",
+      "treatment": "darken overlay 40–60% for text legibility",
+      "damPreference": ["lifestyle", "people", "abstract"]
+    },
+    "useCases": [
+      "Brand manifesto / mission statement",
+      "Launch hero with dramatic mood",
+      "Hiring post with team photo"
+    ],
+    "avoidCases": [
+      "Data-heavy content",
+      "Posts needing multiple bullet points",
+      "Brands without strong photography in DAM"
+    ],
+    "slotCount": 3
+  },
+  "fields": [],
+  "brush": null,
+  "brushAdditional": []
+}
+```
+
+### Valid category values (Phase 23)
+
+| Category string | Slug group |
+|----------------|------------|
+| `"stat-data"` | hero-stat-45, big-number-card, stat-comparison |
+| `"quote-testimonial"` | photocentric-quote, typographic-quote, book-quote-highlight |
+| `"announcement"` | coming-soon-minimal, website-launch-mockup, event-promo |
+| `"photo-collage"` | vintage-scrapbook, fashion-moodboard, memory-grid-4up, asymmetric-photo-collage |
+| `"hero-photo"` | photo-darken-headline, split-photo-feature |
+| `"tips-howto"` | numbered-tips-cover, how-to-step-card |
+| `"personal-about"` | about-me-portrait, hiring-portrait-cta |
+| `"product"` | product-hero-backlit, product-feature-grid, product-callout-macro |
+| `"motivational"` | affirmation-note, handwritten-quote-photo |
+| `"carousel-cover"` | carousel-cover-typographic |

+# about-me-portrait
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A personal introduction layout: italic name at the top, a large arch-cropped portrait in the center, four interest/personality tags flanking the photo on the sides, and a tagline or mission statement at the bottom.
+
+## Structural pattern
+
+Name sits centered at y=100px in italic 72px. The portrait photo (720×820px) sits in the center with a rounded arch top (360px border-radius) creating an organic framing. Four short tags (28px, 500 weight) orbit the photo at mid-height — two on the left column (y=420, y=600) and two on the right (y=380, y=680). A centered tagline spans the bottom zone (bottom:120px, padded 80px each side).
+
+## Content type fit
+
+- Personal brand intro posts
+- Founder / team member meet-and-greet posts
+- Creator or influencer introduction
+- "Hi, I'm [name]" posts for new audience segments
+
+## When to use
+
+- When building a personal brand and introducing yourself to followers
+- When the message is "who I am and what I do"
+- When a conversational, personality-driven aesthetic is the brand voice
+
+## When NOT to use
+
+- For purely professional hiring contexts (use `hiring-portrait-cta`)
+- When the portrait is group shot or landscape-oriented
+- When more than 4 interest tags are needed
+
+## Components
+
+- Centered arch-portrait + name + orbital interest tags + bottom tagline

+# affirmation-note
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A text-only motivational note: category label and date in opposite corners at the top, a bold affirmation statement in the upper-center, a supporting elaboration below, and a handle at the bottom. No imagery.
+
+## Structural pattern
+
+Note category (top-left, y=80px) and date (top-right, y=80px) establish the content series context. The affirmation headline sits at y=340px (96px, bold) — short and commanding. Below it, the body/elaboration expands on the affirmation at bottom:280px (36px, regular weight). Handle at bottom:108px. The layout relies entirely on typography and negative space.
+
+## Content type fit
+
+- Daily reminder or affirmation series
+- Mindset and personal development content
+- Wellness and self-care brand content
+- Weekly motivational format posts
+
+## When to use
+
+- When the affirmation is concise (2–8 words) and the body elaborates
+- When typography and restraint ARE the brand aesthetic
+- When publishing a consistent recurring content series
+
+## When NOT to use
+
+- When a photo would strengthen the message (use `photocentric-quote` or `handwritten-quote-photo`)
+- When the affirmation text is too long to be readable at 96px
+- When the brand is not in the wellness/motivational/personal development space
+
+## Components
+
+- Metadata corners + bold affirmation headline + body elaboration + handle

+# asymmetric-photo-collage
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A 3-photo split with left-dominant composition: one large full-height photo (660px wide, left), and two stacked portrait photos (412px wide, right), separated by thin 8px gaps. A headline and sub-label overlay the large photo near the bottom.
+
+## Structural pattern
+
+The canvas is divided vertically: large left photo (660px × 1350px) and two right-column photos (412px each, stacked with an 8px gap at y=666px). Column gap is 8px. The left photo establishes the primary visual subject. The two right photos provide complementary detail or context. A bold headline (72px) sits near the bottom of the large photo, followed by a small sub-label.
+
+## Content type fit
+
+- Fashion collection posts (hero outfit + detail shots)
+- Portrait + environment + detail compositions
+- Product hero with lifestyle context
+- "New arrivals" or collection announcement posts
+
+## When to use
+
+- When one image should be visually dominant but two supporting images add depth
+- When the three images share a consistent visual language
+- When a brief headline adds editorial positioning to the photos
+
+## When NOT to use
+
+- When all three photos are similar in scale or subject
+- When the headline needs a clean text area (headline overlays the large photo — requires adequate contrast area)
+- When more than 3 images need to be shown
+
+## Components
+
+- Left-dominant 3-panel split + headline overlay

+A single dominant number fills the center of the canvas, with a brief context label above and a short unit description and supporting note below. Maximum typographic impact from one data point.
+
+## Structural pattern
+
+The number sits in the vertical mid-zone at an extreme display size (~320px), visually overwhelming the canvas in a deliberate, graphic way. A small context label (eyebrow) sits 108px from the top. Below the number, a unit label names what is being counted, followed by a one-to-two sentence supporting statement near the bottom. The layout is deliberately minimal — nothing competes with the number.
+
+## Content type fit
+
+- Milestone celebration posts (100K users, first $1M, etc.)
+- Single achievement highlights
+- Anniversary posts anchored by a time-based number
+- "We did the math" data storytelling
+
+## When to use
+
+- When the number itself is the story and needs no supporting context to be striking
+- When you want maximum scroll-stopping power from one metric
+- When the brand has a landmark number worth celebrating in isolation
+
+## When NOT to use
+
+- When comparing two states (before/after, this year vs. last year) — use `stat-comparison`
+- When showing 3+ metrics — use `hero-stat-45` or `data-dashboard`
+- When the number needs a chart or graph to be meaningful
+
+## Components
+
+- Single-number display (context-label → big-number → unit-label → supporting-copy)

+# book-quote-highlight
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A review layout with a header + rating at the top, a cover/product image in the left column with three annotation callouts in the right column, and a featured quote or excerpt at the bottom spanning the full width.
+
+## Structural pattern
+
+The upper zone (top 15%) holds a review header and rating. The mid-zone is split 40/60: a tall product/cover image occupies the left column (68px–448px, y=210–810px), and three short annotation callouts in italic fill the right column. The bottom zone holds a full-width "from the book" label and a featured excerpt quote set at 38px. The staggered right-column callouts at 170px vertical intervals create a natural reading rhythm.
+
+## Content type fit
+
+- Book or course review posts
+- Product annotation / first impression posts
+- "Recommended reading" posts with personal commentary
+- Resource round-up posts featuring one hero item
+
+## When to use
+
+- When you have a product or cover image that can anchor the left column
+- When you want to communicate 3 distinct reactions or highlights
+- When a pull quote from the item itself is the emotional close
+
+## When NOT to use
+
+- When no product image is available (use `typographic-quote`)
+- When more than 3 callout annotations are needed
+- When the excerpt exceeds ~2 sentences
+
+## Components
+
+- Review header panel + rating label
+- Two-column mid-zone (image left / callout annotations right)
+- Full-width excerpt footer

+# carousel-cover-typographic
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A text-only carousel cover: topic tag top-left, a large ghost number behind the headline (creates depth), bold display headline, subtitle, and a swipe CTA badge bottom-right. Pure typographic impact — no imagery.
+
+## Structural pattern
+
+Topic tag at y=108px (wide-tracked caps). A very large ghost number (200px, 8% opacity) sits behind the headline at y=300px, providing depth and hinting at the quantity of items. The headline starts at y=380px (130px, bold) over the ghost number. Subtitle at bottom:300px (36px, regular). Swipe badge at bottom:108px right.
+
+## Content type fit
+
+- Educational carousel series (5 ways to X, 3 rules for Y)
+- Thought-leadership list content
+- Framework or methodology openers
+- Any carousel where the headline is the primary hook
+
+## When to use
+
+- When the carousel covers a listicle-style topic where the count (5, 3, 7) is part of the hook
+- When pure typography IS the brand aesthetic for educational content
+- When the topic tag is part of a recurring series format
+
+## When NOT to use
+
+- For single-frame posts (swipe CTA requires follow-up slides)
+- When a lifestyle photo would strengthen the cover (use `numbered-tips-cover`)
+- When the headline word count exceeds 7–8 words at this scale
+
+## Components
+
+- Topic tag + ghost number + bold headline + subtitle + swipe badge

+# coming-soon-minimal
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A centered, typographic-only coming-soon announcement: brand name, bold headline, teaser line, launch date, and URL — all stacked on a vertical center axis. Maximum restraint for maximum anticipation.
+
+## Structural pattern
+
+Five text elements stacked center-aligned on the vertical midpoint of the canvas. Brand name at ~280px (small, spaced caps). Headline at ~520px (140px, light weight — the anti-bold choice amplifies elegance). Teaser line at ~840px (small, widely tracked). Launch date at ~940px (56px, the concrete commitment). URL anchored at the bottom. The wide vertical gaps between elements are intentional — negative space is the design.
+
+## Content type fit
+
+- Product or brand pre-launch teasers
+- Collection drop countdowns
+- "Something is coming" mystery posts
+- New brand / rebrand reveal sequences
+
+## When to use
+
+- When you have a confirmed launch date and want to commit to it publicly
+- When restraint is the brand signal (premium, editorial, luxury)
+- When the launch itself is the whole story — no product image needed yet
+
+## When NOT to use
+
+- Without a specific launch date (vague "coming soon" undermines credibility)
+- When you have a product photo or mockup to feature (use `website-launch-mockup`)
+- When the announcement is immediate (use `event-promo` for live events)
+
+## Components
+
+- Centered vertical text stack (brand → headline → teaser → date → URL)

+# event-promo
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A full-bleed event announcement: atmospheric photo at reduced opacity behind typography, bold event name centered in the mid-zone, and a semi-transparent info band at the bottom anchoring date, time, and location.
+
+## Structural pattern
+
+The photo fills the full canvas at 45% opacity (the brand background layer darkens it further at generation time). A small presenter line sits near the top (y=100px). The event name is set at 120px in the vertical center zone (y=460–720px). An event description sits below the name. A dark semi-opaque info band (height=240px) anchors the bottom with three columns: date, time, location — each with a small label and bold value.
+
+## Content type fit
+
+- Pop-up markets, craft fairs, and maker events
+- Workshops, retreats, or in-person experiences
+- Brand activations and launch parties
+- Community events and meetups
+
+## When to use
+
+- When the event has an atmospheric photo that can set the scene
+- When the key details are date, time, and location (exactly 3 info items)
+- When building FOMO for an in-person experience
+
+## When NOT to use
+
+- Virtual or online events (no location, info band feels empty)
+- When no event-appropriate photo is available (use `coming-soon-minimal`)
+- When more than 3 info items are needed (band becomes unreadable)
+
+## Components
+
+- Full-bleed background photo + presenter line + bold event name + description + info band (date/time/location)

+# fashion-moodboard
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A three-zone editorial moodboard: large hero photo (top ~49%), a centered typography section with a script accent word and collection title (mid ~21%), and a three-image detail strip (bottom ~21%). An optional quote overlay floats on the hero photo; credits appear at the bottom edge.
+
+## Structural pattern
+
+The hero photo fills the upper ~49% (1080×660px). A season tag floats top-right over the photo. An optional quote overlays top-left in light text. Below the photo, a text zone contains a centered italic script accent (72px, italic) above a bold display title (80px, wide letter-spacing). The bottom detail strip consists of three equal-width cells (~350px each) with 8px gaps, providing visual rhythm and additional imagery. A small credits line sits at the very bottom at high opacity reduction.
+
+## Content type fit
+
+- Seasonal collection moodboards (spring, summer, autumn, winter)
+- Brand identity or aesthetic reveal posts
+- Campaign editorial previews
+- Lifestyle brand world-building posts
+
+## When to use
+
+- When you have 4 images from a consistent editorial session
+- When the emotional/aesthetic story is the primary message
+- When building audience around a brand aesthetic over time
+
+## When NOT to use
+
+- When images come from different color palettes or shooting styles
+- When the post needs a specific offer or CTA
+- When the brand voice is data-driven rather than editorial
+
+## Components
+
+- Hero photo zone + typography zone (script + collection title) + detail strip (3 images) + credits

+# handwritten-quote-photo
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A lifestyle photo at reduced opacity serves as the full-canvas background. A large italic quote sits in the vertical center, followed by attribution name, role, and brand handle near the bottom. The italic style evokes handwritten authenticity.
+
+## Structural pattern
+
+Background photo fills the full canvas at 50% opacity. The italic quote text starts at y=420px (88px, italic, regular weight). Attribution name at bottom:200px (32px, medium) and role at bottom:152px (26px, regular) anchor the source. Brand handle sits bottom-right at bottom:108px.
+
+## Content type fit
+
+- Coach or author quote posts
+- Lifestyle blog or journal posts with a personal insight
+- Partner/client attribution posts
+- Warm motivational content with a lifestyle visual
+
+## When to use
+
+- When you have an atmospheric lifestyle photo that creates emotional context
+- When the quote is attributed to a specific named person
+- When the italic, handwritten aesthetic fits the brand register
+
+## When NOT to use
+
+- When no lifestyle photo is available (use `affirmation-note`)
+- When the quote is longer than ~2 sentences (88px italic overflows the canvas width)
+- When the attribution is anonymous or institutional
+
+## Components
+
+- Full-canvas background photo (semi-transparent) + centered italic quote + attribution + handle

+# hero-stat-45
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A 4:5 portrait adaptation of the hero-stat archetype: bold headline in the upper zone, supporting body copy in the mid-zone, and three key metrics anchored at the bottom.
+
+## Structural pattern
+
+The layout divides the vertical canvas into three clear zones: headline (top, ~44% of height), body copy (mid, transitions region), and stat row (bottom, ~20% of height). The headline is set at a commanding size (~130px) to establish visual dominance. Three stats share equal horizontal space at the bottom, each with a large numeric value and a short descriptor label beneath it. The 4:5 canvas gives the headline more vertical breathing room compared to the square variant, making it suitable for 3–4-word headlines that need visual weight.
+
+## Content type fit
+
+- Annual report or quarterly review posts
+- Campaign performance reveals
+- Brand credibility / social proof posts
+- Service results showcases
+
+## When to use
+
+- When you have exactly 3 concrete metrics that support a narrative
+- When the headline is the primary hook and stats provide proof
+- When the post needs to feel authoritative and data-backed
+
+## When NOT to use
+
+- When you have more than 3 stats (use `data-dashboard` instead)
+- When stats are ranges or qualitative rather than specific numbers
+- When you need to feature a product image or person photo alongside stats (use `split-photo-feature` or `hero-photo-darken`)
+- When the body copy exceeds 2–3 short sentences
+
+## Components
+
+- Stat row (eyebrow → headline → body copy → 3-col stat grid)

+# hiring-portrait-cta
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A hiring/recruitment post: small badge header (We Are Hiring), bold oversized headline (Join Our Team) on the left, rounded-corner team/person photo on the right, short role description, and an apply CTA near the bottom.
+
+## Structural pattern
+
+Badge text at y=108px (small, wide-tracked). The hiring headline (120px, bold) occupies the left column starting at y=220px. A 420×580px rounded-corner photo fills the right column (right:68px, y=300px). Below both, a role description (34px, width:700px) at bottom:260px describes the ideal candidate. The apply CTA sits at bottom:108px.
+
+## Content type fit
+
+- Job opening announcements
+- Team expansion posts
+- Brand ambassador / freelancer recruitment
+- Internship or fellowship calls
+
+## When to use
+
+- When the brand needs to hire and wants a polished, editorial recruitment post
+- When a team photo or professional portrait is available
+- When the CTA is an application link
+
+## When NOT to use
+
+- Personal introduction posts (use `about-me-portrait`)
+- When the role description needs more than 3 lines
+- When no people photo is available
+
+## Components
+
+- Badge + left headline column + right rounded-corner photo + role description + apply CTA

+# how-to-step-card
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A single-step carousel content card: series label and rounded photo in the upper zone, a step number + headline in the right column, full-width body copy below, and a page indicator bottom-right.
+
+## Structural pattern
+
+Series label at y=108px. Left column: rounded 440×560px photo. Right column: italic step number (80px light) at y=200px, bold step headline (64px) below it. Below both columns, a full-width body copy block (34px, y from bottom:230px). Page indicator at bottom-right. The split photo+number/headline zone uses the top 600px; body copy uses the lower zone with generous spacing.
+
+## Content type fit
+
+- Carousel interior slides for tips/how-to series
+- Single actionable tip posts (standalone)
+- Tutorial or protocol step cards
+- Onboarding content
+
+## When to use
+
+- As part of a series started with `numbered-tips-cover`
+- When a single tip or step has a clear headline and 2–4 lines of explanation
+- When a lifestyle photo can illustrate the action or context
+
+## When NOT to use
+
+- As a carousel cover (use `numbered-tips-cover`)
+- When the explanation requires more than 4 sentences (body overflows)
+- When no lifestyle photo is available and the layout feels sparse
+
+## Components
+
+- Two-column upper zone (photo left / step-number+headline right) + full-width body + page indicator

+# memory-grid-4up
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+An asymmetric 4-panel photo grid: one large dominant photo (upper-left), one tall side photo (upper-right), and two equal photos across the bottom. Small caption and date labels overlay the lower-left of the main photo.
+
+## Structural pattern
+
+The grid is composed of two columns (702px + 370px) and two rows (800px + 538px) with 8px gaps. The top-left cell is the dominant visual (~702×800px). The top-right cell is a tall portrait photo (~370×800px). The bottom row splits into two cells with matching heights (~538px). The caption label and date label sit at the bottom edge of the lower-left area.
+
+## Content type fit
+
+- Event or experience recap posts
+- Product launch with environmental + detail context
+- Monthly or quarterly recap posts
+- Behind-the-scenes multi-moment storytelling
+
+## When to use
+
+- When one image should visually dominate the others but all 4 are important
+- When you have a mix of landscape and portrait-oriented photos
+- When the layout needs to feel intentional rather than equal-weight
+
+## When NOT to use
+
+- When all photos are the same crop/orientation
+- When text needs to be the primary message
+- When you only have 2–3 images
+
+## Components
+
+- Asymmetric 4-panel grid (1 large + 1 tall + 2 bottom) + caption overlay

+# numbered-tips-cover
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A carousel cover slide for how-to or tips content: series label top-left, italic "How to" script accent, bold headline, tip count indicator — all left-aligned with an optional right-column accent photo and a swipe CTA bottom-right.
+
+## Structural pattern
+
+Series label sits at y=108px. Italic script "How to" sits at y=300px as a stylistic prefix. The main headline at y=440px is set at 110px bold — the scroll-stopper. A tips count line at y=840px signals what follows in the carousel. An optional 380×480px rounded-corner accent photo fills the right column (right:68px, y=320px). A swipe CTA anchors the bottom-right.
+
+## Content type fit
+
+- Carousel tip series covers
+- How-to instructional content series openers
+- Educational Instagram content with multiple slides
+- Habit, productivity, or skill-building series
+
+## When to use
+
+- When the post is the first slide of a carousel (swipe CTA is the hook)
+- When you have a concrete "how to" premise that can be stated in 4–6 words
+- When the series label provides context for a recurring content format
+
+## When NOT to use
+
+- Single standalone posts without carousel slides following
+- When the how-to premise is too complex for the headline slot
+- When no accent photo is available (the right column will be empty — still works but less compelling)
+
+## Components
+
+- Carousel cover with series-label + script-accent + bold-headline + tip-count + accent-photo + swipe-cta

+# photo-darken-headline
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+Full-bleed hero photo with a gradient darkening overlay at the bottom, allowing a bold headline and sub-copy to sit over the image with legibility. The photo IS the design — text anchors at the bottom.
+
+## Structural pattern
+
+The photo fills the entire canvas. A CSS gradient overlay (transparent at top, 80% dark at bottom) creates a dark zone starting at ~65% of the height. The eyebrow label sits at bottom:370px, headline at bottom:190px (100px, bold), and sub-copy at bottom:80px. The bottom-anchored text zone allows the photo's subject to breathe in the upper portion.
+
+## Content type fit
+
+- Brand manifesto posts
+- Campaign launch hero posts
+- Hiring / join-the-team posts with a lifestyle photo
+- Seasonal or editorial campaign anchors
+
+## When to use
+
+- When you have a compelling hero photo that sets the emotional tone
+- When the message is brief (1 headline + 1 supporting line)
+- When cinematic or editorial mood is the brand register
+
+## When NOT to use
+
+- Without a high-quality photo (dark overlay on a low-quality photo makes it worse)
+- When multiple bullet points or structured information are needed
+- When the photo bottom has complex texture that obscures text even with darkening
+
+## Components
+
+- Full-bleed photo + gradient darkening overlay + bottom-anchored text (eyebrow/headline/sub)

+# photocentric-quote
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A full-width hero photo occupies the upper 56% of the canvas; the lower 44% presents a bold pull-quote with attribution on a dark content field. The photo provides emotional context; the quote delivers the message.
+
+## Structural pattern
+
+The photo fills the upper zone (1080 × 760px) with `object-fit: cover`. The lower zone starts at y=780px and contains a large decorative quotation mark, the quote text set at ~52px, and an attribution line near the bottom. The two zones are clearly delineated — no text overlaps the photo, ensuring legibility without a darkening overlay.
+
+## Content type fit
+
+- Founder / executive spotlight quotes
+- Client testimonials with client photos
+- Team member spotlight cards
+- Partner or influencer quote posts
+
+## When to use
+
+- When you have a strong portrait or lifestyle photo that contextualizes the quote
+- When the quote is attributed to a specific named person
+- When emotional resonance from the photo is needed to give the quote weight
+
+## When NOT to use
+
+- When no strong photo asset exists (use `typographic-quote` instead)
+- When the quote is anonymous or from a public figure without a brand asset
+- When the quote exceeds ~150 characters (text panel gets crowded)
+
+## Components
+
+- Photo hero panel (upper zone) + quote panel (lower zone)

+# product-callout-macro
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A product feature post: large macro/detail product photo fills the upper 52%, followed by a bold callout headline and three feature bullet points in the lower zone, with a CTA near the bottom.
+
+## Structural pattern
+
+Product photo spans the full width at the top (1080×700px). Below it, a bold headline at y=740px (72px, bold) states the product's emotional promise. Three feature points sit below the headline at y=980/1038/1096px (30px each), each prefixed with a bullet dot. A CTA anchors the bottom at bottom:80px.
+
+## Content type fit
+
+- Product launch feature callouts
+- "What makes this different" posts
+- Conversion-focused product posts with proof points
+- Restock or back-in-stock posts with renewed selling points
+
+## When to use
+
+- When the product has 3 clear differentiating features
+- When a macro or detail photo makes the product feel premium
+- When a direct CTA (shop link) is the goal of the post
+
+## When NOT to use
+
+- When more than 3 features need to be listed (the layout has exactly 3 slots)
+- When a full collection needs to be shown
+- When the post is aspirational/editorial without a direct sell
+
+## Components
+
+- Full-width product photo + bold callout headline + 3 feature bullets + CTA

+# product-feature-grid
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A 2×2 product showcase grid with collection headline and subtitle at the top, and four product cells each containing a photo, name, and price.
+
+## Structural pattern
+
+Collection title (52px, bold) and subtitle sit in the upper zone (top:80px–240px). Below, a 2×2 grid fills the remaining canvas with 24px gaps. Each cell contains a photo taking the bulk of the cell height, with a name/price row below. The product grid spans left:68px to right:68px.
+
+## Content type fit
+
+- New collection drops with multiple items
+- Product range overviews
+- Gift guide posts
+- Seasonal product edits
+
+## When to use
+
+- When showing exactly 4 products from the same collection
+- When all product photos share consistent background and lighting
+- When price is part of the story
+
+## When NOT to use
+
+- When products are visually inconsistent (different backgrounds, sizes)
+- For single product highlights (use `product-hero-backlit`)
+- When product descriptions are needed beyond name + price
+
+## Components
+
+- Collection header + 2×2 product grid (photo + name/price per cell)

+# product-hero-backlit
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A product spotlight layout: brand name and bold product name at the top, a large centered product photo (object-fit: contain to show the full item), product description and price below, URL footer at the bottom.
+
+## Structural pattern
+
+Brand label at y=80px (small, wide-tracked). Product name at y=160px (120px display size). Product photo occupies center zone (180px inset, y=380–1020px, 720×640px). Below the photo: description on the left, price on the right, both at bottom:220px. Footer URL is centered at bottom:80px.
+
+## Content type fit
+
+- Product/menu spotlight posts with pricing
+- Single item launch posts
+- Product promotion campaigns
+- Retail or e-commerce announcement posts
+
+## When to use
+
+- When a single product is the hero and the price is part of the message
+- When the product photo is a clean packshot on neutral background
+- When the brand context (name) should anchor the layout
+
+## When NOT to use
+
+- When multiple products need to be shown (use `product-feature-grid`)
+- When the product image is lifestyle (not studio packshot) — the centered contain layout won't fill well
+- When price is not relevant to the post
+
+## Components
+
+- Brand label + product name display + centered product photo + description/price row + footer

+# split-photo-feature
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A vertical split: photo fills the left column (520px wide, full height), editorial text fills the right column (category tag, headline, body, CTA). Clean separation — photo on one side, story on the other.
+
+## Structural pattern
+
+The left column (520px × 1350px) holds a portrait-oriented photo. The right column starts at 560px and holds: category tag (22px, top:108px), headline (80px, top:240px), body copy (30px, top:660px), and a CTA link (bottom:108px). The column separation is achieved by the background layer color showing between the photo edge and the content zone (8px implied gap via positioning).
+
+## Content type fit
+
+- Product feature and editorial posts
+- New arrival announcements
+- Person feature or profile posts
+- "The story behind" content pairing context copy with a visual
+
+## When to use
+
+- When you have a strong portrait-format photo and editorial copy that complement each other
+- When the message needs more than one line (this layout comfortably holds 3–5 lines of body)
+- When a CTA is part of the post
+
+## When NOT to use
+
+- When the photo is landscape-oriented (crops to a very narrow slice)
+- When body copy is too brief (leaves the right panel visually unbalanced)
+- When cinematic full-bleed impact is the goal (use `photo-darken-headline`)
+
+## Components
+
+- Left photo column + right text column (category-tag → headline → body → CTA)

+# stat-comparison
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A two-column before/after layout: headline in the upper zone, two large values split by a vertical divider in the mid-zone, with a brief closing note at the bottom. Optimized for showing transformation through numbers.
+
+## Structural pattern
+
+The canvas is divided into three vertical zones. The upper zone (top 35%) holds an eyebrow label and headline. The mid-zone holds two equal columns separated by a thin vertical line — left column shows the "before" state, right column shows the "after" state. Each column has a small label, a large display number, and a short metric descriptor. The bottom note grounds the comparison with context (timeframe, conditions).
+
+## Content type fit
+
+- Product results / efficacy proof posts
+- Client case study result reveals
+- Campaign performance before/after
+- Challenge or protocol outcome posts
+
+## When to use
+
+- When the story is fundamentally about transformation between two states
+- When both values are specific and dramatically different
+- When you want the contrast to do the visual work without a chart
+
+## When NOT to use
+
+- When comparing 3+ metrics (use `hero-stat-45`)
+- When the transformation is non-quantitative
+- When a percentage change (not the absolute numbers) is more compelling — the layout requires two comparable values to land
+
+## Components
+
+- Two-column comparison with vertical divider (before-label/value/desc vs. after-label/value/desc)

+# typographic-quote
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+Asymmetric typographic layout: a massive display word or short phrase fills the left-center zone; a full-sentence quote sits in a right column. Small metadata labels anchor the top corners; a signature or tagline floats at the bottom.
+
+## Structural pattern
+
+The upper corners carry a series label (top-left) and handle (top-right) at small scale. The dominant display quote word(s) sit at 140px in the left 58% of the canvas starting at y=200px — this is the scroll-stopper. A right column (top:300px, right:68px, width:360px) holds the explanatory quote body at 34px with generous line-height. A signature or tagline rests near the bottom-left in italic style to humanize the layout. No imagery — pure typography.
+
+## Content type fit
+
+- Philosophy and mindset content series
+- Brand manifesto posts
+- Wellness, coaching, and personal development quote posts
+- Daily quote formats with consistent series structure
+
+## When to use
+
+- When typography IS the design — no photo asset available or needed
+- When you have a short, powerful display word (3–6 characters ideal) that can anchor the layout
+- When publishing a recurring series that needs a recognizable visual format
+
+## When NOT to use
+
+- When you have a strong portrait or lifestyle photo (use `photocentric-quote`)
+- When the quote is from a specific named individual with a photo asset
+- When the display phrase is too long to be legible at 140px (> 8 characters per line)
+
+## Components
+
+- Asymmetric two-zone typography (display-word left / body-quote right)

+# vintage-scrapbook
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A 2×2 photo grid fills the entire canvas with 12px gutters. Two small metadata labels (collection name, season/subtitle) sit in the lower-left corner over the grid. Photography is the primary visual message.
+
+## Structural pattern
+
+The CSS grid fills the full 1080×1350px canvas with four equal cells (~534×663px each), separated by 12px gutters that render as the background layer color. A dark overlay sits in the lower-left corner where the collection name (bold, 26px) and season/subtitle (lighter, 20px) are positioned at bottom:52px and bottom:24px respectively. The text is legible against any photo content due to its bottom anchor position.
+
+## Content type fit
+
+- Collection or product launch grid posts
+- Brand moodboard or aesthetic reveal
+- Event or experience recap posts
+- "Our world" multi-shot brand storytelling
+
+## When to use
+
+- When you have 4 visually cohesive photos that tell a story together
+- When the images have consistent color temperature and lighting
+- When photography IS the brand message
+
+## When NOT to use
+
+- When photos have inconsistent lighting (the grid makes inconsistency obvious)
+- When a text message needs primary prominence
+- When only 1–2 images are available
+
+## Components
+
+- Full-canvas 2×2 CSS grid + bottom-left metadata overlay

+# website-launch-mockup
+
+**Platform:** Instagram Portrait (1080 × 1350)
+
+## What it is
+
+A bold launch announcement: large headline text in the upper-left, a screen or mockup image in the right-center, and URL + CTA near the bottom. Shows the thing being launched rather than just announcing it.
+
+## Structural pattern
+
+The left side of the canvas carries the text hierarchy: small announcement type label (top), large bold headline below it (up to 4 words at ~110px). The right column holds a tall mockup/screenshot image (560×700px, right-aligned). Both text and image coexist in the mid-zone without competing — the headline is left-anchored and the image is right-anchored. Near the bottom: URL and a brief CTA.
+
+## Content type fit
+
+- Website or app launch posts
+- Digital product drops (course, template, SaaS)
+- Rebrand or redesign reveals
+- "Now live" portfolio posts
+
+## When to use
+
+- When you have an actual screen, mockup, or product visual to show
+- When the announcement is immediate ("now live") not a countdown
+- When the visual proof (the screenshot) is the main credibility signal
+
+## When NOT to use
+
+- Pre-launch (use `coming-soon-minimal` when the product isn't live yet)
+- When no screen or mockup image exists
+- Physical product launches without a digital visual component
+
+## Components
+
+- Left text column (announcement-type → launch-headline) + right mockup image panel + footer text

+ * - Store reducer: agent-style tool_start (has `toolUseId`, no `tier`) does NOT
+ *   push to activeTools (disambiguates the two payload shapes that share a name)
+ * - Store reducer: permission_prompt adds to pendingPermissions
+ * - Store reducer: budget_warning sets budgetWarnings
+ * - Store action: respondToPermission removes from pendingPermissions optimistically
+ * - Store action: dismissBudgetWarning clears the slot

+ *
+ * We mock @anthropic-ai/claude-agent-sdk so that query() captures the

+ * and input, and yields a result message. Then we exercise:
+ *
+ *  1. Ask-first without trust or prior approval → permission_prompt SSE
+ *     emitted, callback awaits, returns { behavior: 'allow' } after
+ *     approve_once.
+ *  2. approve_session → autoApproved.add(toolName).
+ *  3. deny → { behavior: 'deny', message: ... }.
+ *  4. trusted=true → allow without prompt.
+ *  5. Abort signal → callback resolves with { behavior: 'deny' }.
+ *  6. Always-allow tool → allow without prompt.
+ *  7. never-allow-by-default tool → deny.
+ *
+ * These exercise the real canUseTool wired up inside runAgentImpl, the real

 ## Structural Rules (non-negotiable)
 
@@ -25,21 +29,39 @@ When creating an asset:
 - Only use fonts that appear in the Asset Manifest section of the Brand Brief.
 - Every creation must include a complete SlotSchema based on an archetype.
 - Use the background-layer / content / foreground-layer structure from archetypes.
+- Prefer image-led backgrounds for social posts. When an archetype supports imageRole: 'background' or 'hero', use an actual photo from the DAM (or generate one). Decorative-only backgrounds are the fallback, not the default.
+
+## Brand Assets in CSS
+
+When referencing a brand asset in CSS (\`mask-image\`, \`background-image\`, \`content\`, etc.), use \`/api/brand-assets/serve/{name}\` where \`{name}\` matches the \`name\` field returned by \`list_assets\`. The renderer resolves these URLs to local file paths before Playwright loads the HTML. If the name doesn't exist in the DB, the mask/image silently no-ops — so verify the asset exists by calling \`list_assets\` before referencing it.
 
 ## Intent Gating
 
 - Only modify brand data (patterns, voice guide) when the user explicitly asks.
 - When iterating on a creation, preserve the user's direct edits (from the slot editor) unless they say otherwise.
 
+## Saving Creations
+
+When the user asks for a one-off creation ("create a post", "make a one-pager", etc.) without referencing a campaign, call \`save_creation\` WITHOUT \`campaignId\` — the result lands in the Creations tab as a standalone creation. Only include \`campaignId\` when "Active campaign" in the context below is a real campaign ID, meaning the user is viewing or working inside that campaign. Never ask the user which campaign to use — they can move creations later.

+## Archetype Discovery — filter first
+
+Always call \`list_archetypes\` with a filter before selecting. Start with the most specific filter available:
+1. Filter by \`category\` (e.g. "hero-photo", "stat-data") if you know the content type
+2. Add \`platform: "instagram-portrait"\` to restrict to 4:5 archetypes (preferred default)
+3. Add \`imageRole\` filter if you know whether the post needs photography
+Only call \`read_archetype\` on the 1–2 most relevant candidates from the filtered list.`;

+ * transaction. Historically, abandoned test runs, crashed saves, or hand-wired
+ * test fixtures have left iteration rows pointing to files that were never
+ * created or were cleaned up out of band. The Campaigns view then renders
+ * cards that load "HTML file not found on disk" in place of the preview.
+ *
+ * Safety:
+ *   - `minAgeMs` (default 10 minutes) protects rows mid-save. saveCreation
+ *     writes the file before the DB transaction, but validation / image
+ *     generation can keep a row in an "in-flight" state for several seconds.
+ *     Anything younger than `minAgeMs` is left alone.
+ *   - The singleton `__standalone__` sentinel campaign is never deleted, even
+ *     if all of its child creations are cleaned up. It's a logical bucket
+ *     used by campaignless saves; a re-created sentinel would get a new ID
+ *     and break any UI currently filtered to the old one.
+ *   - Resolution uses the same four strategies the watcher uses to serve
+ *     HTML (see resolveIterationHtmlPath). An iteration is only flagged stale
+ *     when ALL strategies fail.
+ *   - When `dryRun`, the function reports what would be deleted and performs

+invoke: whenever generating social media images for ecommerce-adjacent brands via Gemini image gen API
+---
+
+# Gemini Social Image Skill
+
+You are generating commercial photography for social media — not illustrations, not concept art. The image must earn a scroll stop within the first 0.5 seconds. Every element of the prompt is in service of that.
+
+---
+
+## Core Philosophy
+
+**A great social media image does one of two things:**
+1. Makes the viewer feel something (awe, desire, warmth, freedom)
+2. Makes the viewer feel *seen* (this is their life, or their life they want)
+
+Neither of those goals is achieved by a competent, centered, well-lit subject on a clean background. That is what everyone generates by default. The only way to differentiate is to engineer a specific emotional register from the first word of the prompt.
+
+**The model responds to narrative, not keywords.** A coherent descriptive sentence outperforms a list of tags every time.
+
+---
+
+## Prompt Architecture
+
+Every prompt should have these five layers, roughly in this order:
+
+```
+[STYLE SIGNAL] [SUBJECT + SPECIFICS] [ACTION/STATE] [SETTING] [LIGHT] [CAMERA] [EMOTIONAL BRIEF]
+```
+
+### 1. Style Signal (first 2-3 words)
+Open with the genre of photography. This anchors the entire output.
+- `Cinematic outdoor fitness photography` — signals motion, drama, real environment
+- `Luxury beauty editorial photography` — signals elegance, deliberate composition
+- `Intimate editorial fashion photography shot on film` — signals authenticity, grain, warmth
+- `Extreme macro product photography` — signals texture, detail, close-in drama
+
+### 2. Subject + Specifics
+Describe with precision. Generic descriptions produce generic images. Specificity is the proof.
+- ❌ `woman in athletic wear`
+- ✅ `athletic woman in a burnt orange two-piece athletic set`
+- ❌ `skincare bottles`
+- ✅ `three glass serum bottles with brushed gold dropper caps in amber, rose, and cream`
+
+### 3. Action / State
+What is happening? Still life or motion? The model renders both well.
+- For energy: `running with motion blur on her ponytail and legs`
+- For intimacy: `fingers wrapped around a small espresso cup, looking down slightly`
+- For drama: `performing a powerful dumbbell curl with intense focused expression`
+
+### 4. Setting
+Environments do emotional work. Place the subject deliberately.
+- Cobblestone European alleyway/street = effortless aspiration (fashion)
+- Raw industrial gym, exposed brick = grit and authenticity (fitness)
+- White marble / rose quartz slab = luxury and cleanliness (skincare)
+- Warm oak wooden surface = ritual and life (nutrition/wellness)
+- Coastal path at golden hour = freedom and aspiration (fitness)
+- Cafe window, morning light = quiet self-possession (fashion)
+
+### 5. Light — The Highest-Leverage Variable
+Light direction and quality consistently produced the biggest quality jump in testing. Never leave light unspecified.
+
+**Single-source dramatic light beats even studio lighting every time.**
+
+| Light Type | Effect | Use For |
+|---|---|---|
+| Backlit silhouette at golden hour | Halo effect, emotional drama | Fitness aspiration, outdoor lifestyle |
+| Single overhead tungsten spot | Rim lighting, power, grit | Fitness strength, gym content |
+| Warm morning sidelight | Long shadows on surface, lived-in warmth | Nutrition, morning ritual |
+| Warm amber candlelight | Intimate, sensory, skin glows | Wellness, self-care |
+| Soft window backlight (cafe/interior) | Halo behind subject, film feel | Fashion, lifestyle |
+| Warm backlight through glass | Stained-glass glow effect | Skincare bottles, product |
+| Raking late-afternoon window light | Dramatic directional shadows on texture | Flat lays, still life |
+
+### 6. Camera Direction
+These phrases reliably control composition and depth of field:
+- `85mm portrait lens, shallow depth of field` = intimacy, subject isolation
+- `50mm, film-like quality with slight grain` = authenticity, editorial
+- `low angle looking up / upward angle` = power, drama (especially for fitness)
+- `overhead aerial shot` = ritual framing, flat lay organization
+- `100mm macro lens, razor-thin depth of field` = extreme texture and detail
+- `35mm wide-angle` = environmental context, street feel
+
+### 7. Emotional Brief (closing line — the most important trick)
+End the prompt with the *feeling* the image should create, stated as an editorial intention:
+- `The feeling is freedom, not performance.`
+- `You can almost feel the warmth.`
+- `The mood is quiet and self-possessed.`
+- `The energy is raw, powerful, real.`
+- `Sensual and precise simultaneously.`
+
+This works because it steers the model toward *register* rather than just subject matter. Without it, the model defaults to a neutral, competent interpretation. With it, the model resolves ambiguity toward a specific emotional quality.
+
+---
+
+## Brand Category Playbooks
+
+### FITNESS
+**Best performing patterns:**
+- Outdoor backlit silhouette at golden hour > gym content for aspiration/lifestyle
+- Low angle + single overhead light source + action in gym = raw power content
+- Motion blur (ponytail, legs) is a signal of speed and energy — always include for running shots
+- "The feeling is freedom, not performance" = aspiration; "raw, powerful, real" = strength
+
+**Settings that work:** Coastal paths at sunrise/sunset, industrial gyms (exposed brick, concrete), urban streets at dawn
+
+**Avoid:** Centered neutral pose, even studio lighting, static standing with no tension in the body
+
+**Template:**
+```
+Cinematic [outdoor/gym] fitness photography. [Athlete description] [action with motion details], wearing [specific outfit color + description]. [Setting with atmosphere]. [Specific light source — backlit golden hour / overhead tungsten]. [Camera: low angle upward / 50mm film]. [Emotional brief.]
+```
+
+---
+
+### NUTRITION / SUPPLEMENTS
+**Best performing patterns:**
+- Morning ritual context > isolated product shot every time
+- Extreme macro of the product label + tactile material (powder, liquid) = luxury product photography
+- The model renders product label text reliably — always name the product so it appears in the image
+- The model invents coherent branding details (logo, subtitle) when pushed by a tight macro — let it
+- Warm wood surfaces = daily ritual/routine; cold marble = clinical premium; both are valid, choose by brand voice
+
+**Settings that work:** Warm oak table with morning light, white marble with sidelight, open journal + steam as lifestyle props
+
+**Avoid:** Empty product alone without any props or context; harsh overhead light that flattens the scene
+
+**Template:**
+```
+[Lifestyle product photography / Extreme macro product photography]. [Product name + description] [setting with props that tell a story — journal, mug, morning context]. [Warm morning sidelight / overhead golden morning light creating long soft shadows]. [Camera angle]. [The scene feels like someone's actual morning routine / minimal and striking.]
+```
+
+---
+
+### SKINCARE / BEAUTY
+**Two distinct modes — choose based on content calendar goal:**
+
+**Mode A: Product-Forward (new product launch, feature post)**
+- Three or more bottles, all upright, clearly visible, different sizes or colors
+- Clean or quartz surface, soft diffused light with gentle shadows
+- Organic props: halved fruit, scattered flower petals, blossoms
+- Slightly asymmetric arrangement reads as editorial rather than stock
+
+**Mode B: Editorial / Mood (brand aesthetic, campaign content)**
+- Single backlit bottle on rose quartz or stone slab
+- Warm backlight creates stained-glass glow through the glass — very distinctive
+- Fewer elements, more white space, more tension
+- Combine with petals, a single piece of fruit, very shallow DOF
+
+**The most powerful technique:** Warm backlight through colored glass bottles = stained-glass bokeh circles in the background, glowing bottles, unmistakably luxurious.
+
+**Avoid:** Perfectly symmetrical arrangements (reads as Canva template); harsh studio light that kills the glow
+
+**Template (Mode A):**
+```
+Luxury beauty editorial photography. Three glass serum bottles with [dropper cap material] arranged in an organic asymmetric cluster on a [surface]. [Botanical props]. [Warm backlight / soft diffused light]. 85mm, shallow depth of field. [Color palette description]. All bottles are upright and clearly visible. Photorealistic, editorial luxury beauty, vertical composition. [Emotional brief.]
+```
+
+**Template (Mode B):**
+```
+High-end beauty editorial. A [single / two] glass [bottle type] [state: lying on side / upright catching backlight] on a [surface]. [Warm backlight that creates a glow / stained-glass effect]. Scattered [botanicals]. 100mm macro lens, razor-thin depth of field. [Color palette]. Photorealistic, sensual and editorial. [Emotional brief.]
+```
+
+---
+
+### FASHION
+**Two modes based on content goal:**
+
+**Mode A: Connection / Community content** — use direct gaze
+- Medium to portrait framing (waist up or chest up), subject looks directly at camera
+- Specific styling details: exact clothing colors, accessories, hair
+- European location (stone archway, cobblestone alley, warm limestone walls)
+- 85mm portrait lens, shallow DOF, natural dappled light
+- The direct gaze creates parasocial connection that makes followers feel addressed
+
+**Mode B: Aspiration / Mood content** — use averted gaze
+- Looking down, out a window, at a small object (coffee cup, phone)
+- Interior setting (cafe, gallery, corridor) with strong backlight from window
+- 85mm, film grain aesthetic, morning light creating halo
+- The averted gaze creates introspective, brand-aesthetic energy
+
+**The most important discovery:** Film grain aesthetic (`shot on film`, `warm film grain aesthetic`) consistently produces images that read as real photography rather than AI generation. Always include for fashion.
+
+**Avoid:** Wide walking shots with the subject small in the frame — creates distance and loses connection; any background that reads as generic "city street" without specific architectural detail
+
+**Template (Mode A):**
+```
+Intimate editorial fashion photography. Medium shot of [subject description + specific hair/features] wearing [specific outfit with colors and materials], [specific accessory detail]. [She/He] [action: leaning against / standing beside] [specific setting: stone archway / warm limestone wall] [looking directly into camera / direct gaze, calm and confident expression]. Natural [dappled / warm afternoon] light. 85mm portrait lens, gentle background blur. [Emotional brief.]
+```
+
+**Template (Mode B):**
+```
+Intimate editorial fashion photography shot on film. [Subject description] wearing [specific outfit], [action: looking down / gazing out a window] [with a specific prop: espresso cup, book]. [Interior setting with strong window backlight creating a halo behind the subject]. 85mm portrait lens, extremely shallow depth of field, warm film grain aesthetic. [Emotional brief.]
+```
+
+---
+
+### WELLNESS / SELF-CARE
+**Best performing patterns:**
+- **Hands in the scene is the single most powerful technique.** Any hand contact with a product, water, or material transforms "still life" into "ritual."
+- Overhead aerial format works best for wellness — it gives the sense of a complete ritual scene
+- Warm candlelight > any other light source for wellness. It makes skin glow and creates amber warmth that reads as intimate
+- Water with floating botanicals (rose petals, cucumber, herbs) is consistently evocative — people almost feel the temperature
+
+**Sensory language in the prompt works.** "You can almost feel the warmth" as a closing line pushed the model to produce an image with viscerally evocative warmth quality.
+
+**Settings that work:** White ceramic bath bowls, white linen surfaces, linen tablecloths with raking window light, bath trays
+
+**Props that work:** Lit beeswax candle, terracotta/clay vessels with wooden lids, dried eucalyptus/lavender/herbs, fresh rose petals, cucumber slices, rolled white Turkish towels
+
+**Avoid:** Even overhead lighting with no shadows (kills the sensory quality); too many props with no hierarchy; perfectly symmetrical arrangements (feels generic spa aesthetic)
+
+**Template:**
+```
+Luxury wellness [lifestyle / sensory] photography. [Overhead aerial / close-up] of [hands in contact with product / hands holding / aerial flat lay] [specific bowl / vessel / surface]. [Floating botanicals / props around it]. [Warm amber candlelight / raking late-afternoon window light] [creating specific effect on skin/surface]. [Supporting props on linen surface]. Photorealistic, intimate and sensory, luxury wellness brand, vertical composition. You can almost feel [the warmth / the texture / the calm].
+```
+
+---
+
+## Text Rendering in Images
+
+Gemini is notably strong at rendering product text in images — a genuine competitive advantage.
+
+**Rules for reliable text:**
+- Name the product in your prompt exactly as you want it labeled (e.g., "a canister labeled PURE GREENS")
+- Keep product text under ~25 characters for best rendering
+- The model will invent complementary branding elements (logos, subtitles, taglines) that feel coherent — allow this, it makes images feel more real
+- For extremely tight macro shots of product labels, the model renders text with sharp clarity
+
+---
+
+## Composition Patterns by Platform
+
+| Platform | Best Composition | Why |
+|---|---|---|
+| Instagram Feed | Vertical 4:5, clear visual hierarchy, one strong focal point | Maximizes real estate, algorithm rewards saves |
+| Instagram Stories/Reels Cover | Vertical 9:16, bold and readable at glance | Stories viewed full-screen, thumbnail must work |
+| Pinterest | Vertical 2:3, high information density | Longer dwell time on platform, saves-focused |
+| Square (carousels) | 1:1, clean crop, no important elements in corners | Safe across all contexts |
+
+Always specify `vertical composition` unless there's a specific reason not to.
+
+---
+
+## The Quality Stack
+
+Order these in your prompt to maximize output quality:
+1. **Style signal first** — anchors the entire output
+2. **Subject specificity** — eliminates ambiguous interpretation
+3. **Single dramatic light source** — biggest quality lever
+4. **Camera direction** — controls intimacy and drama
+5. **Emotional brief last** — steers register, fills gaps
+
+Always end with: `Photorealistic, [quality signal: editorial quality / luxury brand aesthetic / magazine quality], [composition: vertical composition].`
+
+---
+
+## Anti-Patterns — Never Do These
+
+| Prompt Pattern | Why It Fails |
+|---|---|
+| Generic subject with no specifics (`athletic woman in sportswear`) | Produces stock photo, not brand content |
+| Even/diffused studio lighting with no direction | Flat, forgettable, no drama |
+| Symmetrical centered composition | Reads as template, not photography |
+| Isolated product with no environmental context | Sells features, not feeling |
+| Abstract/artistic at the expense of product clarity (product not visible/identifiable) | Beautiful but useless for social commerce |
+| Wide walking shot with small figure | Distance kills connection |
+| No emotional brief | Model defaults to competent-but-neutral interpretation |
+| More than ~4 major elements in one scene | Visual noise, no hierarchy, eye has nowhere to go |
+
+---
+
+## The Two Phrases That Consistently Elevate Output
+
+1. **`The feeling is [X], not [Y].`** — Contrasts define register better than pure description. "The feeling is freedom, not performance." "The mood is quiet and self-possessed, not posed."
+
+2. **`You can almost feel [sensory quality].`** — Triggers the model to prioritize sensory evocation. "You can almost feel the warmth." "You can almost feel the weight of the fabric."
+
+Use at least one of these closing lines on every prompt.

+  Gives Claude genuine taste when writing or evaluating social media posts — grounded in platform psychology, algorithmic reality, and the discipline of refusing AI defaults. Use this skill whenever the user asks to write, improve, critique, rewrite, or evaluate a social media post for any platform (Instagram, LinkedIn, TikTok, X/Twitter, Facebook, YouTube, Threads). Trigger also when the user asks to "make this post better", "review my caption", "write something for Instagram", "does this work as a tweet", "write a thread about X", or any variation. If social media content is involved in any way, use this skill — even if the request seems simple.
+---
+
+# Social Media Taste Skill
+
+You are a discerning editor for social media content. Your job is not to produce passable posts — it's to produce posts that would make a good writer proud and a bad writer uncomfortable. You know the difference between a post that *looks* like it will work and one that actually does. You are allowed to have opinions.
+
+---
+
+## The Core Belief
+
+Social media posts fail not because they're wrong, but because they're forgettable. The brain decides in under one second whether to stop scrolling — it's looking for something new, emotionally charged, or personally resonant. Everything that doesn't register as one of those three things gets skipped.
+
+**The real job of a social media post is not to be seen. It is to be felt.**
+
+---
+
+## Step 1: Diagnose Before You Write
+
+Before producing anything, ask:
+1. What platform? (Instagram, LinkedIn, X, TikTok, Facebook, Threads, YouTube — they each have different physics)
+2. What's the actual goal? (Reach/discovery, engagement, saves, conversions, community-building)
+3. Who is the intended audience? What do they believe going in? What would make them feel seen?
+4. Does the user have a draft? If yes, critique it honestly before rewriting.
+
+If the user has specified a platform and goal, go directly to writing. Do not ask for more than you need.

+
+## Step 2: Set the Dials
+
+Before generating content, internalize where this post sits on four axes. These are not checkboxes — they are the lens for every decision.
+
+### DIAL 1: VOICE (1–10)
+- **1–3 (Institutional):** Third-person, brand-first, polished. Works for regulated industries, announcements, press-adjacent content.
+- **4–6 (Professional-Personal):** First-person, expert voice, opinionated but measured. LinkedIn's home.
+- **7–10 (Raw-Personal):** Conversational, vulnerable, idiosyncratic. TikTok, Threads, casual Instagram.
+
+> At VOICE < 4, strip all contractions, casual intensifiers ("honestly", "literally"), and anything that sounds like a person talking.  
+> At VOICE > 7, the post must sound like it came from a *specific* person, not a brand. If it could have been written by anyone, rewrite it.
+
+### DIAL 2: HOOK AGGRESSION (1–10)
+- **1–4 (Earned):** Hook builds slowly. Acceptable only for accounts with existing audience loyalty. Risky otherwise.
+- **5–7 (Direct):** Strong first line. Clear pattern interrupt. Scroll-stopping but not clickbait.
+- **8–10 (Surgical):** First 7 words must do the entire job. Every word is load-bearing.
+
+> At HOOK AGGRESSION > 7, the first line must create an open loop, a contradiction, or a specific surprising claim. "Here's a tip" is banned. "I deleted 3 years of content and doubled my following" is not.
+
+### DIAL 3: SPECIFICITY (1–10)
+- **1–4 (Generic):** Broad claims, universal advice, vague inspiration. Almost always weak.
+- **5–7 (Grounded):** Real examples, named tools, actual numbers, specific outcomes.
+- **8–10 (Hyper-specific):** Exact metrics, dates, named people, precise situations. Specificity IS the proof.
+
+> Specificity is non-negotiable above DIAL 3 > 6. "This changed my life" = vague. "This one habit gave me 3 hours back every day" = specific. Specificity creates credibility faster than any authority signal.
+
+### DIAL 4: FORMAT RESTRAINT (1–10)
+- **1–4 (Maximal):** Emojis, bullet points, hashtags, line breaks everywhere. Often signals low-quality content.
+- **5–7 (Selective):** Line breaks used purposefully. 1–2 strategic emojis or none. 3–5 targeted hashtags or none.
+- **8–10 (Sparse):** Prose-led, minimal formatting, lets the words carry the weight. Signals confidence.
+
+> At FORMAT RESTRAINT > 7, ban all emojis unless one is genuinely irreplaceable. Ban all hashtags except 0–2. Every line break must be earned — it's a beat, not decoration.
+
+---
+
+## Step 3: Priority Hierarchy
+
+Check these in order. Do not skip to polish before structure is sound.
+
+| Priority | What to Check | Why It Matters |
+|----------|--------------|----------------|
+| 1 — CRITICAL | Does the hook stop scroll in ≤7 words? | Algorithms see completion rate. A skipped post is a dead post. |
+| 2 — CRITICAL | Does the post make someone feel something? | High-arousal emotions (awe, curiosity, joy, outrage, FOMO) spread 3× faster than neutral content. |
+| 3 — HIGH | Is it specific enough to be credible? | Specificity does the work of authority. Vague claims are invisible. |
+| 4 — HIGH | Is the format right for the platform? | Carousels on Instagram. Text posts on LinkedIn. Short-form video on TikTok. Each has different physics. |
+| 5 — HIGH | Is there one clear CTA? | One post, one ask. Multiple CTAs cancel each other out. |
+| 6 — MEDIUM | Does it keep users on-platform? | External links are penalized by every major algorithm. |
+| 7 — MEDIUM | Does it invite a response (not demand one)? | "Tag someone who needs this" is spam. A genuine question or provocation earns responses. |
+| 8 — LOW | Hashtag discipline | 3–5 targeted hashtags or none. Hashtag walls (20+) signal spam and lower reach. |
+
+---
+
+## Step 4: Platform-Specific Physics
+
+These are not preferences — they are how the algorithms actually work.
+
+### Instagram
+- **Carousels earn ~109% more engagement per reach than Reels** — use when the goal is saves and comments
+- Reels for discovery, carousels for depth
+- Crop to 4:5 for feed maximum visual real estate
+- Respond to every comment in the first hour — early signals determine distribution
+- Saves > DMs > Comments > Likes in algorithmic weight
+
+### LinkedIn
+- **Text posts outperform images and video** — LinkedIn rewards depth, not spectacle
+- The "see more" break is critical: the first 2 lines must earn the click
+- Personal experience + professional insight > thought leadership > promotional
+- Post 3–5 days/week at consistent times; LinkedIn rewards cadence
+- End with a question — discussion quality is a ranking signal
+- Do NOT put the CTA in the post body; put it in the first comment to avoid distribution penalty
+
+### X / Twitter
+- **Threads and takes** — text dominates
+- First tweet must stand alone as a complete thought; the thread pays it off
+- Specificity beats snark (both work, specificity lasts longer)
+- Controversy generates replies which generate reach — frame the hot take carefully
+- No external links in the post; put them in replies
+
+### TikTok
+- **Hook in first 2 seconds** — literally the first words out of your mouth
+- Completion rate is the primary ranking signal — shorter and tight beats longer and interesting
+- Niche depth beats broad appeal; a 10k micro account in a specific niche can outperform a 500k generalist
+- Post 1–4×/day consistently; TikTok heavily rewards cadence
+- Sound-on assumed; spoken hook matters as much as visual hook
+
+### Facebook
+- **Groups and Reels** — feed posts are deprioritized
+- Community-first content: ask questions, spark discussion, make people feel part of something
+- "Share this with someone who needs it" (used sparingly) subtly boosts distribution
+- Longer personal stories perform well when they have a clear emotional arc
+
+### Threads
+- Early-Threads culture rewards authenticity and low-polish more than any other platform
+- Conversational, reactive, slightly-unhinged energy outperforms polished content
+- Short over long; wit over wisdom
+
+### YouTube (Shorts + Long)
+- **Thumbnail + title do 80% of the work** for long-form
+- Shorts: 5.91% average engagement rate — highest of any short-form format
+- Watch time determines channel-level ranking; never waste your first 15 seconds
+
+---
+
+## Step 5: The Banned List
+
+These are the defaults AI-generated social content reaches for first. They are signals of low effort and damage credibility. **Never produce them unless the context explicitly demands it.**
+
+### Banned phrases
+- "In today's fast-paced world..."
+- "I'm excited to share..."
+- "Game-changer", "revolutionary", "elevate your [X]"
+- "Here's what I've learned:" (as an opener)
+- "The secret to [X] is..."
+- "Stop scrolling."
+- "This is the thread you didn't know you needed."
+- Any opener that begins with "I" on LinkedIn (the algorithm partially suppresses it AND it reads as self-absorbed)
+- "🧵👇" as a standalone tweet before a thread
+- "What do you think? Let me know in the comments!"
+
+### Banned formats
+- Hashtag walls (15+ hashtags)
+- Bullet lists that replace actual prose on LinkedIn and Instagram
+- Motivational quote over a sunset image with no added perspective
+- "Before and after" framings that imply the reader is broken
+- Faux-vulnerability that doesn't reveal anything real ("I almost gave up on my dream...")
+
+### Banned structures
+- Hook → vague claim → vague advice → generic CTA
+- Any post where every sentence ends with an exclamation point
+- Threading together 10 tweets of "hot take" without ever making the actual point
+
+---
+
+## Step 6: The Emotional Test
+
+Before finalizing, run this check:
+
+> **"Does this make someone feel seen, or does it make them feel sold to?"**
+
+If the post is primarily about the writer or the brand, it will underperform. If it makes the reader feel understood, named, or represented — it will travel.
+
+Ask also: **Which of these six emotions does it activate?**
+- **Awe** ("I never thought about it that way")
+- **Curiosity** ("I need to know how this ends")
+- **Joy/Laughter** (genuine, not forced)
+- **Outrage** (used carefully — it travels fast but burns trust)
+- **FOMO** ("I can't miss this")
+- **Nostalgia** ("This is exactly how I felt")
+
+If it activates none of them, rewrite the hook.
+
+---
+
+## Step 7: Finish Work
+
+A post is not done when it is written. Check:
+
+- [ ] Hook: Does the first sentence create genuine tension, curiosity, or surprise?
+- [ ] Specificity: Is there at least one concrete detail (number, name, date, outcome) that couldn't apply to anyone?
+- [ ] Emotion: Would a real person feel something reading this?
+- [ ] Platform fit: Is the format (length, structure, hashtags) right for where this lives?
+- [ ] CTA: Is there exactly one? Is it clear and friction-free?
+- [ ] AI-smell check: Read it aloud. Does it sound like a person or a press release?
+- [ ] Link discipline: If there's an external link, is it in the comment/reply instead of the post body?
+
+---
+
+## Output Standards
+
+### When writing a post
+- Always produce the post first, then a brief note on what you did and why — not before.
+- If the post could work in multiple variants (e.g., high-hook vs. subtle, text vs. carousel format), offer 2 versions with a clear recommendation and rationale.
+- Be willing to say if an idea is weak at its core. A well-written bad idea is still a bad idea.
+
+### When critiquing a post
+- Lead with the diagnosis: what is this post trying to do, and is it positioned to do it?
+- Be specific about what to cut, what to rewrite, and what's working.
+- Never give vague praise. "This is good" tells the user nothing.
+- Offer at least one concrete rewrite of the weakest element.
+
+### When the request is impossible to make good
+- Say so. "This topic doesn't naturally create curiosity or emotion — here's how we'd need to reframe it to have a chance."
+- Offer the best version of a bad idea, but label it honestly.
+
+---
+
+## Variants
+
+Use the right framing depending on what's being asked:
+
+- `--critique` → Evaluate an existing post. Diagnose first, rewrite second.
+- `--thread` → Write a multi-post thread. First post must stand alone. Each subsequent post must add new information, not repeat the hook.
+- `--repurpose` → Adapt content from one platform to another. Don't just resize — rebuild for the platform's physics.
+- `--caption` → Instagram/Facebook caption for an image or video. Assume the visual does 60% of the work; caption handles context and CTA.
+- `--series` → Write 5–10 posts on a single topic. Map the arc (educate → provoke → inspire → convert) before writing.
+
+---
+
+*The goal is not to generate content. The goal is to make something worth reading.*
