Fix horse sprite deploy: cache-bust assets and harden paddock rendering

[Exios66]

Summary

Restores deploy-time asset cache-busting and paddock sprite hardening after merging current main (#67 refactor).

Changes vs main

• docs/index.html — __ASSET_SHA__ query params (consumed by sync-gh-pages.sh)
• docs/css/casino.css — min size on horse sprite canvases
• docs/js/ui/racing-renderers.js — fallback assignHorseSprites if a horse lacks spriteId

Merge resolution

Conflicts against the extracted racing-renderers.js / app split were resolved by keeping mainline modules and re-applying the still-missing cache-bust pieces.

Risk: low. Approved — narrow docs frontend changes (asset cache-busting placeholders, paddock sprite backfill, canvas min dimensions) with bounded blast radius and no policy requiring human review. No reviewers assigned.

Open-PR triage: still valid, but superseded

Status: mergeable, but Checks python/web are red due to Actions billing — not because of these three file changes.

What’s still useful vs main

• __ASSET_SHA__ placeholders in docs/index.html (consumed by scripts/sync-gh-pages.sh)
• Paddock spriteId backfill in racing-renderers.js
• Horse canvas min-width / min-height

Remedy

These unique bits are already re-applied on #92. Prefer merging #92 and closing this PR to avoid duplicate churn. If you keep this branch, ignore the failing Checks jobs until billing is restored (or run uv run pytest -q locally).

Daily open-PR triage (2026-07-26)

Status: superseded + merge-conflicting — do not merge; close instead

GitHub reports CONFLICTING merge state. A three-way merge against current main conflicts in docs/index.html (arcade overlay vs. stale branch), docs/css/casino.css, and docs/js/ui/racing-renderers.js.

More importantly, merging this branch would revert major main features (cabinet boot screen, arcade CRT overlay, playing-card sprites, trading-floor ticker, etc.) while only adding ~16 lines of horse/cache-bust hardening — those fixes are already on main via #92:

• docs/index.html — __ASSET_SHA__ query params on CSS + app.js
• docs/css/casino.css — .horse-sprite-canvas { min-width: 48px; min-height: 36px; }
• docs/js/ui/racing-renderers.js — withHorseSpriteIds() backfill before paddock render

Checks on current main: pytest + RPG smoke pass.

Recommended action: close this PR as superseded by #92. If you still want a fresh branch for audit trail, cherry-pick only the three files above onto current main — but there is nothing left to cherry-pick today.

Daily open-PR triage (2026-07-26)

Status: CONFLICTING and harmful to merge — close instead of resolving conflicts

GitHub reports CONFLICTING / dirty. Resolving conflicts on this branch would not be a safe fix — a three-way merge would revert major main features while adding only ~16 lines of horse/cache-bust hardening that are already on main via #92:

File	Already on main
docs/index.html	__ASSET_SHA__ query params
docs/css/casino.css	.horse-sprite-canvas { min-width: 48px; min-height: 36px; }
docs/js/ui/racing-renderers.js	withHorseSpriteIds() backfill

Conflicts specifically involve removing #arcade-overlay, cabinet boot screen, playing-card sprites, and trading-floor ticker CSS — all post-#92 main work (#94, #91, #108, #110).

No fix PR opened — there is nothing left to cherry-pick; opening another branch would duplicate #92.

Recommended action: close as superseded by #92.
