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.

# Codebase Summary
|
||
|
||
## File Organization
|
||
|
||
### Routing & Layout
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/routes/+layout.svelte` | Root HTML layout. Sets Vietnamese lang, imports Geist font, applies global flex layout. |
|
||
| `src/routes/+page.svelte` | Single page (`/`). Header + SettingsButton, renders player/master/both via `settings.mode`. Indigo→purple gradient branding. |
|
||
|
||
### Shared Components
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/PlayerBoard.svelte` | Reusable player card (9×9 grid rendered as 3 stacked 3×9 mini-cards: Tân Tân / An khang thịnh vượng / Tân Tân tốt nhất). Tall (3:4 on mobile; 3:5 on sm+) cells with condensed bold black numbers (`tan-tan-num` font stack w/ self-hosted Roboto Condensed), white number cells, purple empty cells (dark mode dims via `filter:brightness(0.85)`). Handles crossed state, animated cross-out (200 ms `cross-draw` keyframe), `active:scale-90` press, 10 ms haptic on tap. Two header actions: "Tạo bảng mới" / "Xoá đánh dấu". First-run state shows a faded preview card. Bingo popup tiers: row 1 = standard celebration; row 3+ = falling-emoji confetti rain via CSS `confetti-fall`. Toast "Chờ N" + audio. Accepts `storagePrefix` prop for multi-card isolation. |
|
||
| `src/lib/SettingsButton.svelte` | Gear icon + modal (responsive `max-w-sm sm:max-w-md`). 6 fieldsets: Giao diện (theme pills), Chế độ (3-way mode picker w/ SVG glyphs: player/master/both), Chế độ quản trò (switch row), Tự động xổ (switch + speed slider), Âm thanh (two switches + voice picker), Màu ô trống (10 Excel swatches + custom input in bordered card w/ "Tuỳ chỉnh"/"Mẫu" sub-headers). Boolean toggles use a shared `switchRow` snippet (`role="switch"` + keyboard support). Reset-to-default button. Mounted on `/`. |
|
||
| `src/lib/MasterEmptyState.svelte` | Empty board placeholder for first-run master (mirrors PlayerBoard's preview UX). Displays faded 11×9 grid with "Ấn để bắt đầu ván mới" hint. |
|
||
| `src/lib/MasterPanel.svelte` | Host controls. New game / draw, large "Số vừa xổ" hero token (160 px mobile, 224 px sm+) with `aria-live="assertive"` + auto `scrollIntoView` on each new draw, "Thứ tự đã xổ" history list, 11×9 last-digit-aligned tracking grid (with circular tokens + draw-order overlay). Publishes draws to `call-bus` for player auto-tick. "Xổ số" / "Bắt đầu / Dừng" button bound to auto-call. Mounted conditionally on `/` when `settings.mode !== "player"`; the wrapping section uses `transition:slide` for smooth toggle-in. |
|
||
| `src/lib/PageFooter.svelte` | Footer with tagline ("Made by miti99 with ❤️ SVG icon") + link. Mounted on `/`. |
|
||
|
||
### Game Logic & Coordination
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/game-logic.js` | Stateless utilities: generateGrid (constraint-aware picker — exact 5 per row & per col, ascending-sorted columns, soft "no 3 consecutive filled cols per row" via rejection sampling), saveGrid, loadGrid, saveCrossedState, loadCrossedState, isRowComplete, getWaitingNumber. |
|
||
| `src/lib/call-bus.svelte.js` | Pub/sub for master draws → player auto-tick. Reactive `bus.lastDrawn` slot (emits `{ num, at }`). Used in `mode: "both"` to auto-mark master-called numbers on player board. |
|
||
| `src/lib/vietnamese-number.js` | `numberToVietnamese(n)` — pure utility mapping 0..90 to spoken Vietnamese, with tonal exceptions (15 → "mười lăm", 21 → "hai mươi mốt", 25 → "hai mươi lăm"). Out-of-range falls back to `String(n)`. |
|
||
| `src/lib/voice.js` | Bundled-MP3 playback. Exports `playNumber(n)`, `playWaiting(n)` (sequences cho + N), `playBingo()`, `cancelPlayback()`. Lazy `<audio>` cache, cancel-then-play, token-based cancel ensures stale promises can't resume after a new event. Reads active voice from `settings.voice`; URLs go through `import { base } from "$app/paths"` for basePath safety. |
|
||
| `src/lib/audio-manifest.js` | Re-exports `static/audio/manifest.json` as `VOICES` (array) + `VOICE_IDS` (Set) + `DEFAULT_VOICE`. Manifest is generated by `scripts/generate-audio.py`. |
|
||
| `src/lib/settings-store.svelte.js` | Reactive global UI settings via Svelte 5 runes. Stores 9 keys: `theme` (enum: "auto" / "light" / "dark"), `mode` (enum: "player" / "master" / "both"; replaces legacy `masterMode`), `autoCallEnabled` (bool), `autoCallSpeed` (1–10), `emptyCellColor` (hex), `voiceEnabledMaster` (bool), `voiceEnabledPlayer` (bool), `voiceWaitingNumber` (bool), `voice` (string id matching audio manifest). Persisted to localStorage `loto_settings`. Pushes values to CSS vars and `<html class="dark">` on `:root`. Per-key validators preserve old data. One-shot migration: `masterMode: true` → `mode: "both"`. |
|
||
|
||
### Styling
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/app.css` | Root styles: Tailwind @import, CSS variables (light/dark), Tailwind v4 `@variant dark (.dark *)` for explicit dark-mode class selector, `.loto-grid` & `.master-grid` (9-col), animations (fade-in, pop-in, bounce-slow, spin-slow, toast, cross-draw 200 ms cell mark, confetti-fall 1.6 s), `.cell-crossed` diagonal, `.confetti` falling-emoji helper. |
|
||
|
||
### Tests
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/game-logic.test.js` | 27 unit tests: generateGrid shape (9×9, 5 per row/col, no duplicates), column ranges & ascending sort, no-3-consecutive soft constraint, row completion, waiting number detection, persistence (saveGrid/loadGrid/saveCrossedState/loadCrossedState with validators). |
|
||
| `src/lib/settings-store.test.js` | 31 unit tests: defaults (incl. voice keys), loadSettings (restore 8 keys, apply CSS vars, toggle dark class, handle empty/corrupt), saveSettings, resetSettings, theme toggle (auto → OS pref detection), master mode, auto-call + speed, color validation, voice round-trip + invalid-id fallback. |
|
||
| `src/lib/vietnamese-number.test.js` | 40 unit tests: ones (0–9), teens (10–19 incl. mười lăm), 20–90 incl. mốt and lăm exceptions, out-of-range fall-through. |
|
||
|
||
### Configuration & PWA
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `svelte.config.js` | adapter-static (HTML export), dual basePath via BUILD_PROFILE env, SvelteKit PWA plugin config. |
|
||
| `vite.config.js` | Tailwind + SvelteKit + PWA plugins. codeserver HMR config (port, allowedHosts, hmr). |
|
||
| `package.json` | SvelteKit 2, Svelte 5 (runes), Tailwind 4, Vite, @vite-pwa/sveltekit. Scripts: dev, dev:codeserver, build, build:gh, lint, test, test:watch. |
|
||
| `eslint.config.mjs` | ESLint 9 flat config (@eslint/js + eslint-plugin-svelte). Declares Svelte 5 rune globals. |
|
||
| `jsconfig.json` | Path alias `$lib`, no checkJs. |
|
||
| `.gitignore` | Excludes node_modules, build, .env.local, etc. |
|
||
| `.env.example` | codeserver profile vars (CODESERVER_HOST, CODESERVER_PORT). |
|
||
| `static/_redirects` | Cloudflare Pages: `/* / 301` — every unknown path 301-redirects to homepage. |
|
||
| `static/manifest.webmanifest` | PWA manifest: name, short_name, icons (192/512px), theme colors, display: standalone, scope, start_url. |
|
||
| `static/icons/{192,512}.png` | PWA icons (auto-generated by @vite-pwa/sveltekit from source). |
|
||
| `static/audio/{voiceId}/*.mp3` | Pre-generated Vietnamese voice clips (1–90 + cho + kinh per voice). Generated by `scripts/generate-audio.py`. SW caches at runtime (CacheFirst). |
|
||
| `static/audio/manifest.json` | Voice list `{ id, edgeName, label, gender }[]`. |
|
||
| `scripts/generate-audio.py` | One-shot Python script: generates 92 clips per voice, writes manifest. |
|
||
| Service Worker (auto) | @vite-pwa/sveltekit generates `/pwa-manifest.json`, `/sw.js`. App shell precache ~353 KB. Auto-update mode with reload toast. |
|
||
|
||
## Key Data Structures
|
||
|
||
**Grid**: 9×9 2D array of numbers (1–90). Empty cells are 0.
|
||
**Crossed**: 9×9 2D array of booleans indicating marked cells.
|
||
**Master State**: `{ called: number[], remaining: number[] }` — drawn and undrawn numbers.
|
||
|
||
## Storage Keys (localStorage)
|
||
|
||
| Key | Use Case |
|
||
|-----|----------|
|
||
| `loto_grid` | Player's card numbers. |
|
||
| `loto_crossed` | Player's marked cells. |
|
||
| `loto_master` | Host's drawn/remaining numbers. |
|
||
| `loto_settings` | Global UI settings: `{ theme, mode, autoCallEnabled, autoCallSpeed, emptyCellColor, voiceEnabledMaster, voiceEnabledPlayer, voiceWaitingNumber, voice }`. |
|
||
|
||
Old `masterMode` bool is migrated on load: `masterMode: true` → `mode: "both"`. `loto_master_card_*` keys no longer written but old saved data untouched.
|
||
|
||
## Component Hierarchy
|
||
|
||
```
|
||
RootLayout
|
||
└── HomePage (/) ← single page; any other URL redirects to /
|
||
├── [if settings.mode !== "master"]
|
||
│ └── PlayerBoard (storagePrefix="loto")
|
||
├── [if settings.mode !== "player"]
|
||
│ └── MasterPanel (publishes to call-bus on draws)
|
||
└── PageFooter

## Key Functions
|
||
|
||
| Function | Location | Effect |
|
||
|----------|----------|--------|
|
||
| `pickFilledCols()` | game-logic.js | Per-row column selection that guarantees exact 5 per col (forces any col whose remaining quota equals rowsLeft, random-fills the rest). |
|
||
| `generateGrid()` | game-logic.js | Builds 9×9; ascending-sorted numbers per column. |
|
||
| `isRowComplete()` | game-logic.js | Boolean: all non-zero cells in row crossed? |
|
||
| `getWaitingNumber()` | game-logic.js | Returns the single uncrossed number in row, or null. |
|
||
| `handleCellClick()` | PlayerBoard.svelte | Toggle crossed[row][col]. |
|
||
| `saveGrid()` / `loadGrid()` | game-logic.js | localStorage with prefix-based keys. |
