tiennm99 f899b09631 feat: UI polish v2 + installable PWA with offline audio
Phase 1 — Vietnamese-safe font + master empty state:
- Add @fontsource/roboto-condensed (700 weight, all subsets including
  Vietnamese). font-display:swap. tan-tan-num now resolves the bundled
  face on Android instead of system Arial Narrow.
- New MasterEmptyState.svelte: ghost 11×9 grid + "Chế độ Quản trò"
  pill + readiness microcopy. Replaces the bare line of text in
  MasterPanel's no-game state.

Phase 2 — Mode picker icons, color picker layout, header polish:
- Inline SVG glyphs above each mode button (player card / megaphone /
  two stacked cards). Communicates role at a glance.
- Color picker wrapped in a single bordered card with "Tuỳ chỉnh"
  and "Mẫu sẵn" sub-headers.
- "Mặc định" → "Đặt lại" with a bordered chip style — clearer
  affordance than the previous near-invisible footer link.
- Header subline: drop tracking-[0.28em] all-caps SaaS look; replace
  with dash-flanked lantern band ("— 🏮 Hội chợ TN1 —") for
  fairground mood.

Phase 3 — Installable PWA + offline audio:
- @vite-pwa/sveltekit with autoUpdate. Precache app shell (~353 KB
  → 213 entries) PLUS the default voice's 92 clips so first-install
  is fully offline-capable. Alternate voices fall through to a
  CacheFirst runtime rule (cached on first play, 30-day TTL,
  maxEntries: 400 for future-proofing).
- New static/manifest.webmanifest (Lô tô — Hội chợ TN1, theme #1565c0,
  background #0a0f1f, standalone, vi).
- Icons: 192/512 standard + 512 maskable, generated from a single
  rose-amber-gradient SVG source.
- app.html: manifest link, dual theme-color meta (light + dark),
  apple-touch-icon, apple-mobile-web-app-capable for proper
  standalone launch on iOS Safari.
- _headers: add manifest-src + worker-src to CSP; no-cache on /sw.js
  and /manifest.webmanifest so deploys propagate.

Tests: 115/115 pass. Build clean (305 precache entries, 0 glob
warnings).

Reviewer concerns (addressed):
- maxEntries bumped 200 → 400 (was barely enough for 2 voices).
- Default voice precached so offline-first promise holds without
  requiring users to play every clip online first.
- "do NOT add skipWaiting" comment added next to autoUpdate.

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.
