The main leaderboard SPA is now served at / (index.html) and the
standalone replay viewer lives at /replay.html. This removes the
_redirects workaround in index-builder that patched over the inverted
entry points.
- Rename web/app.html → web/index.html (main SPA)
- Rename web/index.html → web/replay.html (standalone viewer)
- Update vite.config.ts: main→index.html, replay→replay.html
- Remove _redirects injection from deploy.go verifyMergedOutput
- Update pages.json routes and README dev URL

The replay viewer was baked into index.html (served at /) while the
leaderboard app was at /app.html. Add a _redirects file so visitors
landing on / get redirected to the main leaderboard app.

- Add ReplayPlayer to type imports in replay-viewer.ts
- Add explicit type annotation for entry parameter in replay.ts transcript map
- Fixes TypeScript compilation errors for §15.3 screen reader transcript feature
Implementation complete:
1. engine/thumbnail.go - New thumbnail rendering package
- GenerateMatchThumbnail() creates 640x360 PNG thumbnails
- Renders grid, bots, cores, walls, energy with player colors
- SelectThumbnailTurn() chooses most interesting turn
- Pure Go stdlib image rendering (no canvas required)
2. cmd/acb-worker - Upload thumbnails to B2 alongside replays
- uploadThumbnail() generates PNG and uploads to B2
- Key: thumbnails/{match_id}.png, content-type: image/png
- Called after match completion, non-blocking on failure
3. cmd/acb-index-builder/deploy.go - Promote thumbnails to R2
- promoteRecentReplays() copies both replays AND thumbnails from B2 to R2
- Thumbnails promoted to warm cache alongside replay promotion
4. cmd/acb-index-builder/generator.go - Populate thumbnail URLs
- buildPlaylistMatch() now includes thumbnail_url field
- URL pattern: https://r2.aicodebattle.com/thumbnails/{match_id}.png
- Enables playlist cards and embed OG tags to show preview images

Add metrics server startup and HTTP middleware to acb-api, generation
counter metric to evolver, and R2 cache size metric to index builder.
Also remove dead measureR2CacheSize reference from index builder main.

- Fix deploy.go to query actual table names (series_games not series_matches,
join through series_games for seasons instead of non-existent season_matches)
- Add playlist_matches table to exempt match IDs from R2 pruning
- Pre-build lookup maps for O(1) playlist match filtering instead of O(n²)
- Enhance home page featured replay to prefer AI-enriched matches
- Add enrichment test coverage (shouldEnrich criteria validation)

Implement auto-curated playlists in the index builder: 12 playlist types
(closest finishes, upsets, comebacks, marathons, rivalry classics, etc.)
with weekly highlight curation. Add DB persistence, R2 pruning exemptions,
frontend pages, and AI commentary enrichment pipeline.

Replace os.ReadFile+os.WriteFile with io.Copy so large files (e.g. the 21MB
demo-replay-v2-6p.json) are never fully loaded into RAM during copyWebAssets.

wrangler creates .wrangler/tmp relative to its working directory.
The container runs as non-root user acb with WORKDIR=/app (root-owned),
so mkdir /app/.wrangler/tmp fails with EACCES. Setting cmd.Dir=/tmp
gives wrangler a writable CWD while keeping the /data output path
(absolute) unchanged.

Per plan §11.1, the index builder reads PostgreSQL and generates all JSON
index files for Cloudflare Pages deployment:
- main.go: Build cycle orchestration with configurable timeout, self-restart
- config.go: Environment-based configuration with sensible defaults
- db.go: PostgreSQL data fetching for bots, matches, series, seasons, predictions
- generator.go: JSON index generation (leaderboard, bots, matches, playlists)
- deploy.go: Cloudflare Pages deployment via wrangler, R2 warm cache pruning
- Dockerfile: Multi-stage build with Go + Node.js + wrangler CLI
- main_test.go: Tests for config, index generation, playlists
Index builder runs on 15-minute cycles, deploys to Pages every ~90 minutes,
and prunes R2 warm cache weekly to stay within 10GB free tier.
