tiennm99 918fb1cda9 chore(pwa): tighten audio cache eviction (30d → 7d, purgeOnQuotaError)
Workbox's CacheFirst rule for /audio/*.mp3 used a 30-day age-based
TTL. Approximate LRU by dropping to 7d — a voice clip stays cached as
long as it's played at least once a week, otherwise it falls out and
re-fetches on next play. Each clip is <200KB and same-origin so the
re-fetch cost is negligible. Also flip purgeOnQuotaError so the
runtime cache yields first under storage pressure.

Default voice precache (vite.config.js additionalManifestEntries)
unaffected — it's a separate workbox flow with its own revision.

Lô tô

Bàn số của trò chơi "Lô tô" — SvelteKit app.

Single page (/). The host enables "Chế độ quản trò" in settings to reveal the master panel inline below their player card; called numbers get spoken aloud in Vietnamese using bundled MP3 clips (no runtime TTS).

See docs/ for architecture, code standards, and deployment.

Development

npm install
npm run dev

Inside code-server (reverse proxy)

cp .env.example .env.local
# edit .env.local: set CODESERVER_HOST and CODESERVER_PORT
npm run dev:codeserver

Open https://<CODESERVER_HOST>/absproxy/<CODESERVER_PORT>/.

Use /absproxy/{port}/, not /proxy/{port}/ — the latter strips the path prefix and breaks the SvelteKit base path.

Build

npm run build         # default — root basePath, for Cloudflare Pages
npm run build:gh      # /loto basePath, for tiennm99.github.io/loto manual export

Static export to build/. Deployed to Cloudflare Pages from main (set up via the CF dashboard — see docs/deployment-guide.md).

Regenerating audio

Vietnamese voice clips live in static/audio/{voiceId}/. Generated once with edge-tts (free, no API key) — runtime never calls TTS. To regenerate (e.g., to add a new voice that Microsoft ships, or to change wording):

pip install edge-tts
python3 scripts/generate-audio.py

The script auto-discovers every vi-* voice and writes a manifest the app reads on next reload.
