Subject: [PATCH 1/3] feat(primitives): add the primitives layer contract and
 Cf:Button (#52)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cf-ui shipped 14 structural components and no primitives, so a consuming app
abstracted its rare markup and hand-wrote its common markup. This lands the
contract for all of Tier 1 and the first component against it.

The prop contract is settled for the whole tier at once, not per component,
because primitives compose: an icon sits inside a button, a badge inside a
heading. Four axes, each a closed set — variant, size, state, level — declared
in cf_ui/primitives.py and documented in docs/primitives.md.

The classes are deliberately duplicated between primitives.py and the
templates, because they have to be. daisyUI compiles through Tailwind, whose
scanner reads source text: a class assembled at render time is tree-shaken out
of the build with no error and an unstyled page as the only symptom. Emitting
it from Python has the same effect. So the templates spell every class out
longhand and primitives.py is the reviewable source of truth, with the parity
test binding them in both directions — every class in the map must appear
literally in the templates, and every class in the templates must be in the
map or on a short explicit list of layout utilities.

That duplication is also why validate() exists. A literal {% if %} chain has no
else: handed variant="purple" it matches nothing and renders a correct-looking
element with no colour. Every primitive calls the guard once, so a bad value
raises at the call site naming the values that would have worked.

Open questions from the issue, decided:

- Icons stay slot-only. cf-ui supplies sizing and alignment; the caller
  supplies the glyph. Adopting an icon set would make a UI kit choose its
  consumers' icon vendor, which is the mistake axes.py already refuses for
  brand colour.
- href switches the element. state="disabled" with an href renders an <a>
  with no href attribute plus role="link" and aria-disabled="true" — an <a>
  cannot be disabled, and leaving the href on produces a control that is still
  focusable, still Enter-activatable, and still middle-clickable.
- Primitives take no markup props at all. Everything that can carry markup
  arrives through the slot, under the caller's own escaping policy, so
  docs/escaping.md needed no new rule.
- grid is left undecided and tracked as Tier 3. Four frameworks ship
  12-column systems with different vocabularies and daisyUI ships none, so it
  is a genuine asymmetry rather than a thin adapter.

Bulma and Foundation both call the base class `button`, and daisyUI mirrors
Bootstrap's `btn`, so a default-props button is genuinely identical across two
pairs of themes. test_theme_dispatch's distinctness check now renders a state,
the same remedy it already used for the Bootstrap/daisyUI alert collision.

Component counts in four existing guards now derive from themes.COMPONENTS
rather than a literal 14, with the registry asserted non-empty so the derived
form cannot pass over nothing. test_theme_dispatch keeps its independent
literal list, which is what stops the chain circling.

+# Primitives
+
+The 14 components cf-ui shipped through 0.2.0 are all **structural** — card,
+modal, navbar, table. Primitives are the layer underneath: the small,
+high-frequency elements that structural components are built out of and that
+consuming apps otherwise hand-write everywhere.
+
+They differ from structural components in one way that shapes everything
+below: a primitive is used hundreds of times per app, so its prop contract has
+to be settled once, for the whole set, before any of it is implemented. A
+button that spells its colours `variant` while a badge spells them `type` is a
+worse API than either choice on its own.
+
+## The shared vocabularies
+
+Four axes, each a **closed set**, declared in
+[`cf_ui/primitives.py`](https://github.com/fsecada01/component-framework-ui/blob/master/src/cf_ui/primitives.py).
+An unknown value raises `PrimitiveConfigError` naming the values that would
+have worked — it does not fall through to an unstyled element.
+
+| Axis | Values |
+|---|---|
+| `variant` | `primary` `secondary` `success` `warning` `danger` `info` `neutral` |
+| `size` | `small` `normal` `large` |
+| `state` | `normal` `loading` `disabled` |
+| `level` | `1`–`6` |
+
+Seven variants, not "whatever the framework ships". All five frameworks can
+express all seven, though two collapse a pair onto one class — Foundation has
+no informational button colour, so `info` renders as `secondary` rather than
+cf-ui inventing a class Foundation's own CSS does not define. A vocabulary cut
+down to the poorest framework would make the richer ones useless; one built for
+the richest would make `info` mean nothing in Foundation.
+
+`normal` is always the framework's default and always maps to *no class*. That
+is a real entry in the map, not a gap — the completeness test treats a missing
+key as the failure, so the two cannot be confused.
+
+## Which primitive takes which axis
+
+| Primitive | `variant` | `size` | `state` | `level` | Status |
+|---|:-:|:-:|:-:|:-:|---|
+| `button` | ● | ● | ● | | **Shipped** |
+| `badge` | ● | ● | | | Contract settled |
+| `heading` | | ● | | ● | Contract settled |
+| `label` | | ● | | | Contract settled |
+| `icon` | | ● | | | Contract settled |
+
+`label` and `icon` take no `variant` on purpose. A label's colour belongs to
+the field it labels and an icon's to whatever contains it; giving either its
+own would create two sources of truth for one colour.
+
+`heading` separates `level` from `size` because they answer different
+questions — `level` is the document outline (`<h1>`…`<h6>`, which screen
+readers navigate by) and `size` is how big it looks. Coupling them forces a
+choice between a correct outline and a correct visual hierarchy.
+
+## How they compose
+
+Primitives nest through the **slot**, never through props:
+
+=== "JinjaX"
+
+    ```jinja
+    <Cf:Button variant="primary" size="small">
+      <i class="fas fa-plus"></i>
+      Add item
+    </Cf:Button>
+    ```
+
+=== "django-cotton"
+
+    ```html
+    <c-cf.button variant="primary" size="small">
+      <i class="fas fa-plus"></i>
+      Add item
+    </c-cf.button>
+    ```
+
+There is deliberately no `icon="fa-plus"` prop on `Cf:Button`. An icon prop
+would have to accept either a class name or raw markup: the first ties cf-ui to
+one icon vendor, and the second is an unescaped-markup prop on the single most
+frequently used component in the package. The slot has neither problem.
+
+Once the `icon` primitive lands it occupies that same slot position, adding
+sizing and alignment around the glyph — it does not change how the two nest.
+That is the whole reason the contract is settled for the set before any of it
+is built.
+
+## `Cf:Button` / `<c-cf.button>`
+
+| Prop | Default | Notes |
+|---|---|---|
+| `variant` | `"neutral"` | See the vocabulary above |
+| `size` | `"normal"` | |
+| `state` | `"normal"` | `loading` renders the framework's spinner; `disabled` is described below |
+| `href` | `""` | Non-empty renders an `<a>`; empty renders a `<button>` |
+| `type` | `"button"` | Only applies to the `<button>` form |
+| `full_width` | `false` | |
+| `extra_class` / `class` | `""` | `extra_class` in JinjaX, `class` in cotton — `class` is a Python reserved word |
+| slot | — | The label |
+
+### Disabled links
+
+`state="disabled"` with an `href` renders an `<a>` **without an `href`
+attribute**, carrying `role="link"` and `aria-disabled="true"`.
+
+An `<a>` cannot be disabled. Leaving the `href` on and styling it grey
+produces a control that is still focusable, still activatable by Enter, and
+still followed on middle-click — disabled to sighted mouse users only.
+Dropping the attribute is what actually removes it from the tab order, and
+`aria-disabled` is what tells assistive technology why.
+
+If you need a disabled control that is genuinely inert, prefer omitting `href`
+so it renders a real `<button disabled>`.
+
+## Escaping
+
+The contract in [Escaping](escaping.md) applies unchanged: every cf-ui Jinja
+template wraps its body in `{% autoescape true %}`, so a hostile prop is
+escaped whatever the surrounding environment does, and a prop carrying real
+markup must be `markupsafe.Markup`.
+
+Primitives take **no markup props at all**. Everything that can carry markup
+arrives through the slot, where it is the caller's own template output and
+governed by the caller's own escaping policy:
+
+| Surface | Escaped by cf-ui | Notes |
+|---|---|---|
+| `variant`, `size`, `state`, `level` | n/a | Validated against a closed set before they reach the template |
+| `href`, `type`, `extra_class` | Yes | Ordinary attribute values |
+| slot content | Caller's policy | Where an icon's `<svg>` or `<i>` goes |
+
+`icon` is the one primitive whose slot is *expected* to hold markup, and it is
+still the slot rather than a prop — so passing a `Markup` value is a visible,
+per-call decision at the call site rather than a package default.
+
+When Tier 2 lands, `prose`/`content` will be the one component that exists to
+wrap caller-supplied HTML. It will need its own explicit statement here; the
+rule above is not sufficient for it.
+
+## Why the classes are written out longhand
+
+Open a theme partial and you will find every class spelled literally:
+
+```jinja
+class="btn{% if variant == 'primary' %} btn-primary{% elif variant == 'danger' %} btn-error{% endif %}"
+```
+
+rather than the obvious `btn-{{ variant }}`. This is required, not stylistic.
+daisyUI compiles through Tailwind, whose scanner reads source **text** — a
+class name assembled at render time is never seen, so it is removed from the
+build. No error, no warning, an unstyled page as the only symptom. Emitting the
+class from Python has exactly the same effect, which is why
+`cf_ui.primitives.classes_for()` exists for tests and consumers but is not used
+by the shipped templates.
+
+The cost is that the vocabulary lives in two places: `primitives.py` and ten
+template files. `tests/unit/test_primitives.py` binds them in both directions —
+every class in the map must appear literally in the templates, and every class
+in the templates must be in the map or in a short, explicit list of layout
+utilities. Neither copy can move alone.
+
+That duplication is also why every primitive template calls the guard once:
+
+```jinja
+{{ cf_ui_validate("button", variant=variant, size=size, state=state) }}
+```
+
+A literal `{% if %}` chain has no `else`. Handed `variant="purple"` it matches
+nothing and renders a correct-looking element with no colour. The guard turns
+that silence into an exception at the call site.
+
+!!! note "The guard needs the installer"
+
+    `cf_ui_validate` is bound by `install_cf_ui` (FastAPI and Litestar) and by
+    the `cf_ui` template library (Django), alongside the axis globals. A
+    primitive rendered on a bare `Catalog()` with no installer raises
+    `'cf_ui_validate' is undefined` — the same requirement
+    `cf_ui_root_attrs()` already has.
+
+## Regenerating
+
+`primitives.py` is the single source of truth;
+`static/cf_ui/cf_ui_primitives.json` is a build product of it — the
+machine-readable export of the vocabularies and class maps, mirroring
+`cf_ui_axes.json`. Edit the module, then:
+
+```bash
+just primitives
+```
+
+and commit both. A drift test fails the build otherwise.
+
+## Not yet implemented
+
+`badge`, `heading`, `label`, and `icon` have settled contracts above but no
+templates yet — they are registered in `PRIMITIVES` and deliberately **not** in
+`themes.COMPONENTS`, so referring to one raises a clear `ThemeError` rather
+than a `TemplateDoesNotExist` at first render.
+
+Tier 2 (`box`/`surface`, `prose`/`content`) and Tier 3 (`grid`) are tracked
+separately. `grid` in particular is not a settled question: Bootstrap, Bulma,
+Foundation, and Fomantic all ship 12-column systems with different
+vocabularies, while daisyUI ships none and defers to Tailwind utilities — so a
+daisy `grid` would emit raw utility classes while the other four emit framework
+classes. That is a genuine asymmetry rather than a thin adapter, and it is
+being decided on its own rather than inside this layer.

+"""Primitive vocabularies — the closed sets behind ``variant``/``size``/``state``.
+
+:mod:`cf_ui.axes` answers *what does this app look like*. This module answers
+the narrower question the primitives ask: *which of a fixed set of roles does
+this button play*. Same discipline, same reason — an open-ended ``variant``
+string produces a different button in every consumer, and the closed set is
+what makes "primary" mean one thing across five CSS frameworks.
+
+Why the classes live here **and** in the templates
+--------------------------------------------------
+
+They are duplicated on purpose, and the duplication is guarded.
+
+daisyUI compiles through Tailwind, whose scanner reads source *text*. A
+template that writes ``btn-{{ variant }}`` hands Tailwind nothing to find, so
+every variant class is removed from the build — silently, with an unstyled
+page as the only symptom (``docs/daisyui.md``). Emitting the class from Python
+has exactly the same effect. So the templates must spell every class out
+literally, in full, one ``{% if %}`` branch per value.
+
+That would normally mean the real vocabulary lives in ten template files and
+nothing states it. Hence this module: it is the reviewable source of truth,
+the input to ``cf_ui_primitives.json`` that the Tailwind plugin safelists from,
+and the thing ``tests/unit/test_primitives.py`` holds the templates against in
+both directions. Neither copy is allowed to move alone.
+
+Why :func:`validate` exists
+---------------------------
+
+A literal ``{% if %}`` chain has no ``else``. Handed ``variant="purple"`` it
+emits nothing at all and renders an unstyled element — not an error, not a
+warning, just a button that looks wrong. Every primitive template therefore
+calls :func:`validate` once, in a position that renders its (empty) result, so
+a bad prop raises where it was passed instead of surfacing as a visual bug
+three screens away.

+
+**Loudness.** A literal ``{% if variant == 'primary' %}`` chain emits *nothing*

+notices, so every primitive template calls the guard once and a bad prop
+raises there.
+
+**Parity.** The classes cannot be emitted from Python: daisyUI compiles through
+Tailwind, whose scanner reads source *text*, so a computed class name is
+tree-shaken out silently (see ``docs/daisyui.md``). The templates must
+therefore spell every class literally — which means two copies of the same
+knowledge, one in ``primitives.py`` and one in 10 template files. The parity

Subject: [PATCH 2/3] feat(primitives): badge, heading, label and icon across
 five themes (#52)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Completes Tier 1. `button` landed in the previous commit with the contract;
this adds the remaining four primitives, each as a cotton wrapper plus five
theme partials and five JinjaX templates, and closes acceptance criterion 1.

`primitives.py` gains a fifth axis, `emphasis` (`normal` / `subtle`). It
replaces what started as a `subtitle` boolean on `heading`: Bulma's `title`
and `subtitle` are mutually exclusive, so the boolean forced the base class
to carry a value the map could not express, and `classes_for` returned a
string that was wrong for that theme. Promoting it to an axis also fixed a
real daisyUI defect — `opacity-60` existed only in template text, invisible
to `cf_ui_primitives.json`, so a Tailwind build would have shaken it out.

Two guards were weaker than they read, both found by mutation:

* `test_{every_jinja_primitive,the_cotton_wrapper}_calls_the_guard` checked
  only that the string `cf_ui_validate` appeared. Deleting `emphasis=emphasis`
  from the heading wrapper survived both. They now assert every axis the
  component declares is actually passed to the call.
* The `for=for` trip-wire on the label wrapper had no test at all. `for` is a
  Python reserved word so the prop is `for_id`, but django-cotton accepts
  `for` happily and would render a `<label>` with no `for` attribute — valid
  HTML, broken control association, silent. Three tests now pin it: the wrong
  spelling raises, the right one renders, and an absent one does not trip.

Also fixes a pre-existing bug the primitives work surfaced: Django's comment
regex has no DOTALL, so a `{# #}` opened on one line and closed on another
never forms a comment token and renders as page text. Six shipped partials
were leaking paragraphs of rationale prose into consumers' HTML. All six now
use `{% comment %}`; `tests/unit/cotton/test_comment_syntax.py` guards it.

 ## [Unreleased]
 
+### Added — a primitives layer: button, badge, heading, label, icon (#52)
+
+- **Five new components, on all five themes, in both template sets.**
+  `<Cf:Button>` / `<c-cf.button>`, and the same for `Badge`, `Heading`,
+  `Label`, `Icon`. cf-ui shipped 14 *structural* components and no primitives,
+  which is why adoption stalled: measured against a real consumer, `button`
+  was the single most-used CSS-framework class in the codebase (204 uses) and
+  cf-ui had nothing for it, while `modal`, `tabs`, `panel` and `breadcrumb`
+  had zero uses between them.
+
+- **`src/cf_ui/primitives.py` is the closed vocabulary and the class map.**
+  `variant`, `size`, `state`, `level` and `emphasis` are fixed sets; a value
+  outside one raises `PrimitiveConfigError` naming the values that would have
+  worked. Which primitive accepts which axis is declared, so
+  `<Cf:Badge state="loading">` raises rather than rendering a badge with no
+  loading state.
+
+- **The classes are spelled out longhand in the templates, on purpose.**
+  daisyUI compiles through Tailwind, whose scanner reads source *text* — a
+  class assembled at render time (`btn-{{ variant }}`, or one returned from
+  Python) is tree-shaken out of the build with no error and an unstyled
+  element as the only symptom. So `primitives.py` and the templates hold the
+  same knowledge twice, and a bidirectional parity test in
+  `tests/unit/test_primitives.py` fails the build the moment they disagree —
+  in either direction. `classes_for()` exists for tests, docs and
+  outside-the-templates consumers; nothing in the shipped templates calls it.
+
+- **`static/cf_ui/cf_ui_primitives.json`** is generated from the module by
+  `just primitives`, the way `cf_ui_axes.json` is generated from `axes.py`,
+  and a drift test fails if the committed copy is stale.
+
+- **Escaping and accessibility are decided once, in the component.** A
+  disabled `<a>` renders `aria-disabled="true"` and *no* `href` — an anchor
+  without one is not focusable or activatable, so this is the only spelling
+  where "disabled" is more than cosmetic. An icon is either decorative
+  (`aria-hidden="true"`) or named (`role="img"` plus `aria-label`), never
+  both, and `role="img"` makes it a leaf so the caller's glyph markup is not
+  descended into. Primitives take slot content rather than markup props, so
+  `docs/escaping.md` needs no new rule.
+
+- **`docs/primitives.md`** documents the shared contract, composition, the
+  per-theme places an axis is legitimately inert, and why the classes are
+  longhand. Tier 2 (`box`/`surface`, `prose`) and Tier 3 (`grid`) are tracked
+  separately so this could ship on its own.
+
+### Fixed — multi-line `{# #}` comments rendered into the page
+
+- **Six shipped cotton partials leaked their own source comments as page
+  text.** Django's comment regex is `\{#.*?#\}` without `DOTALL`: `{# #}` is
+  single-line only, so a comment opened on one line and closed on another
+  never forms a comment token and every line in between is emitted verbatim.
+  Five bootstrap partials and one daisy partial were affected —

+`normal` is the **middle step**, not "whatever the framework does with no
+class". Usually those coincide and it maps to no class at all — a real entry in
+the map, not a gap, since the completeness test treats a *missing* key as the
+failure.
+
+Two things follow from that, and both are visible to consumers:
+
+**Sometimes `normal` needs a class.** Bulma's `.tag` defaults to its smallest
+step, so a normal badge maps to `is-medium` in order to line up with a normal
+button. The shared vocabulary is the whole point — `size="normal"` has to mean
+one thing across primitives, or sharing it buys nothing.
+
+**Sometimes `size` does nothing.** Bootstrap and Foundation ship no badge size
+classes, so all three values map to no class and a Bootstrap badge renders
+identically at every size. cf-ui does not fake this with font-size utilities:
+Bootstrap's `fs-*` scale bottoms out *larger* than a default badge, so it
+cannot express "small" and would be a wrong-direction lie. Switching
+`CF_UI_THEME` can therefore change whether `size` has any effect on a given
+primitive.
+
+## Colour is not a channel on its own
+
+A `danger` badge and a `success` badge differ only by hue. If the badge's own
+text does not carry the meaning, that is a
+[WCAG 1.4.1](https://www.w3.org/WAI/WCAG22/Understanding/use-of-color.html)
+failure, and it is not one cf-ui can fix from inside the component:
+
+```html
+<!-- Fails: "4" means nothing without the colour -->
+<c-cf.badge variant="danger">4</c-cf.badge>
+
+<!-- Passes: the text carries it -->
+<c-cf.badge variant="danger">4 failed</c-cf.badge>
+```
+
+The variant sets the colour. Making the meaning legible without it is the
+caller's obligation.

+`emphasis` started life as a `subtitle=True` boolean and was promoted, because

+## The axes are not all equally useful on every theme
+
+This is the honest cost of one vocabulary across five frameworks, and it is
+worth knowing before you reach for an axis:
+
+| Primitive | Where an axis does less than you'd expect |
+|---|---|
+| `badge` | `size` is **inert** on Bootstrap and Foundation — neither ships badge size modifiers |
+| `icon` | `size` is **inert** on Foundation, which has no icon wrapper and no font-size scale. On Bootstrap the scale is mixed: `small` is em-relative and composes inside a `btn-sm`, `large` is absolute and does not |

+Bootstrap's `fs-*` scale, for instance, bottoms out *larger* than a default
+badge, so using it for `size="small"` would be a wrong-direction lie rather
+than a fallback.

+| slot | — | The label text |
+
+!!! warning "The attribute is `for_id`, not `for`"
+
+    `for` is a Python reserved word, so JinjaX cannot express it. django-cotton
+    *can*, which is the hazard: `<c-cf.label for="email">` would render valid
+    HTML with no `for` attribute at all and a silently broken label/control
+    association. The cotton wrapper routes any stray `for` through the guard,
+    so it raises `PrimitiveConfigError` instead of rendering wrong.
+
+The required indicator is a single `<span role="img" aria-label="required">*</span>`
+rather than a hidden-glyph-plus-visually-hidden-text pair, because Fomantic
+2.9.3 ships no visually-hidden utility — that approach would have given four
+themes one accessibility mechanism and the fifth another. Fomantic's own
+`.required::after` is deliberately not used: generated content disappears under
+print and high-contrast stylesheets, and its announcement is inconsistent.
+
+## `Cf:Icon` / `<c-cf.icon>`
+
+| Prop | Default | Notes |
+|---|---|---|
+| `size` | `"normal"` | Inert on Foundation; mixed scale on Bootstrap |
+| `label` | `""` | Empty ⇒ decorative. Non-empty ⇒ the accessible name |
+| `extra_class` / `class` | `""` | |
+| slot | — | Your `<i>`, `<svg>`, or `<span>` |
+
+The accessibility decision is most of what this component buys you, and it is
+the part hand-written icon markup usually gets wrong:
+
+```html
+<!-- Decorative: skipped by screen readers entirely -->
+<c-cf.icon><i class="fas fa-star"></i></c-cf.icon>
+<span aria-hidden="true">…</span>
+
+<!-- Meaningful: announced as "Delete item", and not descended into -->
+<c-cf.icon label="Delete item"><i class="fas fa-trash"></i></c-cf.icon>
+<span role="img" aria-label="Delete item">…</span>
+```
+
+The two are mutually exclusive by construction, so a labelled icon can never
+also be `aria-hidden`. `role="img"` matters as much as the label: it makes the
+wrapper a leaf for assistive technology, so the caller's meaningless glyph
+markup is not descended into.
+
+cf-ui ships no icons and depends on no icon set. Bootstrap assumes Bootstrap
+Icons, Bulma assumes Font Awesome, daisyUI assumes nothing — there is no
+class-level abstraction spanning all five, and adopting one would make a UI kit
+choose its consumers' icon vendor.

+   one. `.ui.grey.header` only sets `color`, so emphasis and size stay independent, which
+   is the whole point of this component.
+
+   `size` also has no `medium` step to map `normal` onto: Fomantic ships mini, tiny, small,
+   large, big, huge and massive, with nothing between small and large. Emitting no size
+   class would fall back to the *tag's* size and re-couple size to level, so `normal` takes

+{# `emphasis="subtle"` is `grey`, not Fomantic's own `sub` header, and that is

+   *after* every size variation (`.ui.small.header` … `.ui.massive.header`) at
+   identical specificity (0,3,0), so source order hands it the cascade and the
+   `size` axis silently stops doing anything — an h2 carrying `ui header
+   massive sub` renders at .857em, the same as a tiny one. `.ui.grey.header`
+   only sets `color`, so emphasis and size stay independent, which is the whole
+   point of this component.
+
+   `size` also has no `medium` step to map `normal` onto: Fomantic ships mini,
+   tiny, small, large, big, huge and massive, with nothing between small and
+   large. Emitting no size class would fall back to the *tag's* size and
+   re-couple size to level, so `normal` takes `large` (1.71em) — the token
+   reads oddly, the rendered size does not. #}

+"""A multi-line ``{# #}`` renders into the page, so no cotton template has one.

Subject: [PATCH 3/3] fix(primitives): declare what each axis value becomes;
 add djLint (#52)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Addresses the three findings from the review on PR #53. All three orbited
one gap: the vocabulary system knew every axis's *values* but nothing about
what a value turns into, so the empty-value rule, the class-map rule and the
missing `type` guard each had to be decided by hand.

`AXIS_KINDS` closes it. An axis's value becomes a `class`, a `tag` or an
`attribute`, and that single fact decides both whether the axis needs a
per-theme class map and whether an empty value is benign. Django resolves a
missing variable to "" and the cotton wrappers forward props
unconditionally, so an empty class-valued axis must pass — unstyled is the
right outcome for a missing `variant`. An empty tag- or attribute-valued one
raises, because it renders malformed markup, and the message names the kind
and the values that would work. `CLASS_VALUED` is derived from `AXIS_KINDS`;
no theme may map a non-class axis; both are tested. The five dead
`"level": {"1": "", ...}` class-map entries are gone.

`type` (button/submit/reset) becomes a real axis with a vocabulary and a
guard — it was the second tag/attribute-valued axis the old `LEVELS` comment
warned would arrive.

`ALIASES` declares props whose HTML spelling cf-ui cannot use. `for` is a
Python reserved word, so the label's prop is `for_id`, and django-cotton
silently discards undeclared attributes — `<c-cf.label for="email">`
rendered valid HTML with no `for` at all. The wrapper now forwards the HTML
spelling into the guard purely so it can be rejected by name.

Two guards were weaker than they read: `test_*_calls_the_guard` asserted only
that the string `cf_ui_validate` appeared, and deleting `emphasis=emphasis`
or `size=size` from the call left it green. They now assert every declared
axis is passed. Every new mechanism here was mutation-proved: disabled, watched
fail (12 failures), restored.

Also adds djLint to prek and the justfile with
`single_attribute_per_line = true`, reformatting 107 cotton and 95 jinja
templates. A cf-ui template's whole contract lives in its opening tag, and
they were authored on one line because Django has no whitespace-control
syntax. Verified rather than assumed: all 190 primitive renders (5 themes x
19 components x 2 engines) are byte-identical with whitespace stripped, and
the parsed DOM matches except for a space added after `;` in inline styles.
It is not allowed near `class="..."` values, where added whitespace changes
the rendered bytes. One assertion did depend on attribute layout
(`"required>" in html`) and is now anchored to the `<input>` element instead.

+  empty-value rule derivable rather than case-by-case. Django resolves a
+  missing context variable to `""` and the cotton wrappers forward props
+  unconditionally, so an absent class-valued axis has to be benign — it yields
+  an unstyled element, which is exactly what a missing `variant` should do. An
+  absent *tag*- or *attribute*-valued one does not: an empty `level` has no
+  `<h?>` to render, so it raises and the message says which kind of thing was

+  theme may map a non-class axis, and both are enforced by tests — which is
+  also how `type` (`button` / `submit` / `reset`, the HTML default being

+  `<c-cf.label for="email">` used to render valid HTML with no `for` attribute

+  django-cotton silently discards attributes a component does not declare. The
+  wrapper now forwards the HTML spelling into the guard purely so it can be

+- **`prek` now reformats and lints `templates/cotton/**.html` and
+  `templates/jinja/**.jinja`.** Four hooks pinned at djLint v1.43.1, two per
+  tree, because `profile` is one global setting and the two trees are

+  `just check` now includes the lint pass.
+
+- **`single_attribute_per_line = true` is the point of the exercise.** A
+  cf-ui template's entire contract lives in its opening tag — `<c-vars>`
+  declares every prop, and a theme partial's element carries a literal
+  `{% if %}` chain per axis. Authored on one line, because Django has no
+  whitespace-control syntax and the safe default was "emit no whitespace", a
+  wrapper's prop list was a 100-character run read character by character.
+  107 cotton and 95 jinja templates were reformatted.
+
+- **Checked rather than assumed.** Whitespace *between* attributes is
+  insignificant in HTML; whitespace *inside* a `class` value is not — it
+  changes the rendered bytes and defeats every substring assertion in the
+  suite — so djLint is not allowed near the class chains. All 190 primitive
+  renders (5 themes × 19 components × 2 engines) came out byte-identical with
+  whitespace stripped, and the parsed DOM matched except for djLint adding a
+  space after `;` in inline `style` attributes. One assertion did depend on
+  layout — `"required>" in html`, which relied on the attribute being last
+  before the bracket — and is now anchored to the `<input>` tag itself, which
+  is what it always meant.

+## What an axis value becomes, and why it matters
+
+The third column of that table is not decoration. It is the one fact that
+decides two separate things.
+
+**Whether the axis has a per-theme class map.** Class-valued axes do. `level`
+and `type` do not, because there is nothing to map — the value *is* the tag
+name, or the attribute value.
+
+**Whether an empty value is allowed.** For a class-valued axis it is: the class
+is simply not emitted, and you get a valid element that is merely unstyled.
+That tolerance is load-bearing rather than lax — Django resolves a missing
+context variable to `""`, and every cotton wrapper forwards its props
+unconditionally, so a guard that rejected empty values would reject ordinary
+renders.
+
+For `level` and `type` an empty value is *not* benign, so it raises:
+
+```
+<c-cf.heading :level="section.depth">   # depth is None
+
+PrimitiveConfigError: heading needs a level — it becomes the element's tag,
+so an empty one renders malformed markup rather than unstyled markup.
+Pass one of: 1, 2, 3, 4, 5, 6
+```
+
+Without that check the render succeeds and emits `<h class="title">Section</h>`.
+`<h>` is not an element. Browsers parse it as an unknown inline, and it still
+picks up the `title` class — so it *looks* like a heading while being absent
+from the document outline and unreachable by screen-reader heading navigation.
+It is the exact silent failure the guard exists to convert into an exception,
+in the one axis where an empty value degrades to malformed rather than
+unstyled.
+
+`type` is the same shape with a sharper edge. HTML's missing-value default for
+an **invalid** `<button type>` is `submit` — so `type="sumbit"` does not render
+an inert button, it renders one that submits the enclosing form. cf-ui defaults
+to `button` precisely to avoid that, and an open set would have let a typo undo
+it silently.

+
+    `for` is therefore a **declared alias** — `primitives.ALIASES` maps it to

+

+    PrimitiveConfigError: label takes no 'for' — use 'for_id'.

+
+### What the alias table does and does not catch
+
+`ALIASES` covers props whose natural **HTML spelling** differs from cf-ui's —
+the name a caller will reach for first. Today that is one entry, and adding a
+theme or a primitive does not change it.
+
+It does **not** catch arbitrary misspellings. `<c-cf.icon labl="Delete item">`
+still renders a decorative icon with the accessible name silently dropped,
+because django-cotton discards any attribute a component does not declare —
+for every cotton component in every project, not just cf-ui's. That is a
+property of the template engine, not something a wrapper can close from the
+inside. Treat cf-ui's prop names as exact.
+
+The JinjaX side behaves the same way for a different reason: an undeclared
+attribute lands in `attrs`, which cf-ui's templates do not render.

-`for=for` is a trip-wire, not a prop. The attribute is named `for_id` because
-`for` is a Python reserved word and JinjaX cannot express it — but
-django-cotton accepts `for` happily, so <c-cf.label for="email"> would render
-valid HTML with no `for` attribute and a silently broken label/control
-association. Routing it through the guard turns that into a
-PrimitiveConfigError. `label` declares no `for` axis, so any non-empty value
-raises; an absent one resolves to "" and is skipped.
+`for=for` forwards the HTML spelling into the guard so it can be rejected
+rather than dropped. It is not a prop: the attribute is `for_id`, because
+`for` is a Python reserved word and JinjaX cannot express it. django-cotton
+accepts `for` happily and discards it, so <c-cf.label for="email"> would
+render valid HTML with no `for` attribute and a silently broken label/control
+association. `primitives.ALIASES` declares the mapping and validate() raises
+naming `for_id`; an absent one resolves to "" and is skipped.
 
 `{% comment %}`, not `{# #}`: Django's `{# #}` is single-line only, and a
 multi-line one renders every line in between as literal text into the page.
