Migrate build and deployment pipeline from Cloudflare Pages to GitHub Pages. Adds production-ready deploy workflow in deploy-github-pages.yml with proper artifact handling. Removes Cloudflare-specific tooling: wrangler config, _headers, _redirects, and CSP hash injection scripts (no longer needed with GitHub Pages static hosting). Updates package.json build scripts and all project documentation to reflect new deployment target and simplified architecture.

Shipped
Three-Mode Rendering + Master Auto-Tick (2026-04-27)
mode: "player" | "master" | "both"replacesmasterMode: boolean- New
call-bus.svelte.jscoordinates master draws → player auto-tick in "both" mode - "Quản trò đọc số" voice now speaks Chờ/Kinh on master in "both" mode
- One-shot migration:
masterMode: true→mode: "both"
UI Polish v2 + Installable PWA (2026-04-27)
- Font: Roboto Condensed self-hosted via @fontsource (Latin + Vietnamese subsets), swapped into
tan-tan-numstack - Empty State: New
MasterEmptyState.sveltecomponent for first-run host (mirrors player UX) - Mode Picker: 3-way segmented toggle with inline SVG glyphs (player/master/both)
- Color Picker: Bordered card with "Mẫu" (presets) + "Tuỳ chỉnh" (custom input) sections
- Header Polish: Decorative dashes flanking subline (replaced all-caps tracking)
- PWA: @vite-pwa/sveltekit generates SW + manifest. App shell precache (~353 KB). Audio runtime caching (CacheFirst). Auto-update w/ reload toast. Works offline at fairground (no signal venues)
Idea Phase
Undo Last Cell
Allow player to undo the most recent cross/uncross action. Requires change history or state snapshot. Status: Idea (low priority)
Considered Phase
Multiplayer Sync (Real-time)
Host and players connect via WebSocket to sync called numbers and state. Requires backend server. Would enable:
- Decoupled devices (players' phones, host's laptop on big screen)
- Remote tournaments
- Master board auto-updates all players in real-time
Consideration: Out of scope for static export. Requires major refactor (SvelteKit API routes + WebSocket server). Deferred indefinitely.
i18n Beyond Vietnamese
Internationalization (English, Chinese, etc.). Requires extraction of all Vietnamese strings and i18n library (next-intl). Status: Considered (low demand for non-Vietnamese users)
Undo/Redo System
Full undo/redo stack with history navigation. Adds complexity to state management. Status: Considered (YAGNI for now)
Testing
Component Tests (Planned)
- PlayerBoard with mocked localStorage, $state/$derived verification
- MasterPanel with different game states
E2E Tests
- Player flow: generate card → click cells → verify bingo popup
- Host flow: new game → draw numbers → verify board state
Tech: Playwright
Future Enhancements (Speculative)
Export/Import Card
Allow player to export their grid as image or JSON, import someone else's card. Use Canvas API or print-friendly CSS.
Leaderboard / Stats
Track games won, time per bingo, etc. Requires server-side persistence. Out of scope for static export.
Accessibility Improvements
- ARIA labels for grid cells
- Keyboard navigation (arrow keys to move, Enter to toggle)
- Screen reader support
Custom Number Range
Host selects range (e.g., 1–75 for American bingo) instead of hardcoded 1–90. Requires config UI and refactor of game logic constants. Out of scope per Lô tô hội chợ Tân Tân focus.
Different Grid Sizes
Support 8×8 or 10×10 grids, or 3×9 European Bingo 90 tickets. Out of scope — variant locked to 9×9 Tân Tân format.
Two-line / Full-house Win Tiers
European Bingo 90 patterns. Out of scope — Tân Tân uses single-line "Kinh!" only.
Decision Rationale
All decisions follow YAGNI (You Aren't Gonna Need It), KISS (Keep It Simple), DRY (Don't Repeat Yourself):
- No multiplayer sync → adds server dependency, breaks static export (GitHub Pages)
- No i18n → Vietnamese-only community, localizing adds complexity
- Unit tests implemented → critical paths (constraints, persistence, settings) now have automated coverage
- Component/E2E tests deferred → small codebase, manual testing sufficient for UI flows
- No undo/redo → simple game, mistakes are play experience
- Svelte 5 runes → cleaner reactivity than hooks, smaller mental model
Future work gates on real user demand, not speculation.
