The toast above the card was disconnected from where the user actually looks (the 9×9 grid). Two-part redesign per /ck:research + /ck:brainstorm: - Chip moved to the vertical center of the card with bg-amber-500/75 + backdrop-blur-sm + pointer-events-none on the wrapper. Taps still pass through to the cells underneath; auto-hide stays at 5s. - Persistent 1.6s breathing pulse on the cell holding the awaited number — amber inset ring + soft outer glow, dimmed in prefers-reduced-motion to a static ring. Material 3-style cadence picked over scale-bounce because the grid is dense and bouncing cells would smudge neighbours. Pulses scale to multiple simultaneous waiting rows (Set-keyed by "row,col"). aria-label gains "đang chờ" so screen readers pick it up.
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.
