Wire assetManifest into live renderers — retire gang_members.png sheet and emoji tokens

[BrandDead]

Why

frontend/src/assets/assetManifest.ts catalogs portraits, full-bodies, top-downs, street states, vehicles, and environments — but zero components import it. Every live renderer (TopDownBlock, StreetBlock, CanvasStreetRenderer/V3) draws units from the legacy 4-frame gang_members.png sheet (5.9 MB rendered as 28px tokens) plus emoji and flat colored cells. This is the single biggest reason expensive art exists but the game looks like placeholders. Broken manifest references were already repaired on claude/street-war-graphics-repo-q3519i.

Scope

• TopDownBlock: render member tokens from characterAssets[role].topdown (with the repaired manifest), consume block.topdownBgUrl, and stop hardcoding memberName: 'Member' / role: 'dealer' on placement
• CanvasStreetRendererV3 (now on main via Establish paid MVP readiness foundation #76): standing actors from streetIdle/streetAim/streetHit/streetDowned instead of the legacy sheet; vehicle from vehicleAssets.luxury_sedan_black_001 layers instead of procedural rectangles
• StreetBlock: actors from manifest full-body/street assets; keep streetBackdropUrl consumption
• Central preloader keyed off the manifest (no per-component hardcoded URLs)
• Generate the missing streetIdle assets for dealer, lookout, driver, shooter (only enforcer exists) and a shooter streetAim
• Delete/deprecate GameSprite's pixelated 4-frame path once no consumer remains

Acceptance

No emoji, no gang_members.png, and no flat-color role circles visible anywhere in block or combat views.

Relates: #77 (visual stack), #45.

Progress — core wiring landed in #83 (d971f18)

Done:

• ✅ Central assetResolver service keyed off the manifest (existence-verified URLs, per-state fallback chains, preloading, canvas chroma-defringe)
• ✅ TopDownBlock renders aerial block art under a translucent grid + circular portrait tokens; consumes topdownBgUrl; placement identity fix (no more hardcoded 'Member'/'dealer')
• ✅ StreetBlock renders photoreal street sprites (dealer/shooter/enforcer) on real night-street backdrop; portrait chips for roles without street art
• ✅ CanvasStreetRendererV3 standing actors draw hi-res defringed street art with legacy fallback
• ✅ No emoji / gang_members.png / flat-color tokens in the default block + combat paths for roles with art

Visual evidence: docs/qa/2026-07-20-*.png · Report: docs/REPORT_2026-07-20_GRAPHICS_WIRING.md

Remaining (blocks full acceptance):

• ⬜ Generate missing sprites: street-idle for dealer/lookout/driver, shooter aim, full lookout + driver street sets (those roles fall back to portrait chips / legacy sheet)
• ⬜ Vehicle cutouts with real alpha (sedan top-down + side are RGB with baked backgrounds) — overlaps Asset pipeline cleanup: chroma fringe, missing alpha, oversize files, runtime budget #79; cars remain procedural until recut
• ⬜ Retire the legacy gang_members.png fallback path once every role has street art
