tiennm99 ad537ee4a6 feat(voice): bundled Vietnamese voice calls (master + player)

Speak the called number on master draw, "Chờ N" when a row is one
away, and "Kinh" on bingo. No runtime TTS API — clips are
pre-generated by `scripts/generate-audio.py` (free edge-tts) and
shipped as static MP3s under `static/audio/{voiceId}/`.

- src/lib/vietnamese-number.js + test (40 cases): tonal exceptions
  mười lăm / hai mươi mốt / hai mươi lăm
- src/lib/voice.js: lazy <audio> cache, token-based cancellation,
  cho+number sequencer, on-unmount cleanup
- src/lib/audio-manifest.js: re-exports static/audio/manifest.json
- scripts/generate-audio.py: discovers every vi-* edge-tts voice,
  writes 92 clips per voice + manifest.json
- static/audio/manifest.json: placeholder until user runs the script
- src/lib/settings-store: +voiceEnabledMaster/voiceEnabledPlayer/voice
  with per-key validators
- src/lib/SettingsButton: new "Âm thanh" fieldset (toggles + voice
  picker rendered from manifest)
- MasterPanel.handleDrawNext: playNumber(next) + cancel on new game
- PlayerBoard $effect: playWaiting/playBingo beside toast/popup;
  cancel on regenerate / clear

To materialize the MP3s on first install:
    pip install edge-tts
    python3 scripts/generate-audio.py

Tests: 98 pass (40 number + 31 settings + 27 game-logic).

Raw Blame History

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`	Player page (`/`) — the ONLY page. Header + SettingsButton, PlayerBoard, conditional MasterPanel (when `settings.masterMode`), PageFooter. 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 (3:5 on mobile; wider on sm+) cells with condensed bold black numbers (`tan-tan-num` font stack), white number cells, purple empty cells by default. Handles crossed state, bingo popup, "Chờ X" toast. Two header actions: "Tạo bảng mới" (regenerate grid) and "Xoá đánh dấu" (clear all marks, keep grid — only shown when a grid exists). Accepts `storagePrefix` prop for multi-card isolation. Empty cells use `--empty-cell-bg` CSS var from settings store.
`src/lib/SettingsButton.svelte`	Gear icon + modal. 5 fieldsets: Giao diện (theme auto/light/dark), Chế độ quản trò (master mode toggle), Tự động xổ (auto-call + speed 1–10s), Âm thanh (voice toggles for master + player + voice picker from manifest), Màu ô trống (10 Excel color swatches). Reset-to-default button. Mounted on `/`.
`src/lib/MasterPanel.svelte`	Host controls. New game / draw, "Số vừa xổ" hero token, "Thứ tự đã xổ" history list, 11×9 last-digit-aligned tracking grid (with circular tokens + draw-order overlay). No host's own player card (the player already has one above). "Xổ số" / "Bắt đầu / Dừng" button bound to auto-call. Mounted conditionally on `/` when `settings.masterMode === true`.
`src/lib/PageFooter.svelte`	Footer with tagline ("Made by miti99 with ❤️ SVG icon") + link. Mounted on `/`.

Game Logic

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/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 8 keys: `theme` (enum: "auto" / "light" / "dark"), `masterMode` (bool), `autoCallEnabled` (bool), `autoCallSpeed` (1–10), `emptyCellColor` (hex), `voiceEnabledMaster` (bool), `voiceEnabledPlayer` (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.

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), `.cell-crossed` diagonal.

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

File	Purpose
`svelte.config.js`	adapter-static (HTML export), dual basePath via BUILD_PROFILE env.
`vite.config.js`	Tailwind + SvelteKit plugins. codeserver HMR config (port, allowedHosts, hmr).
`package.json`	SvelteKit 2, Svelte 5 (runes), Tailwind 4, Vite. 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 (lines 16–22).
`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 assets are served first so this only fires on misses.
`static/audio/{voiceId}/*.mp3`	Pre-generated Vietnamese voice clips (1–90 + cho + kinh per voice). Generated once by `scripts/generate-audio.py` (edge-tts). Runtime never calls TTS.
`static/audio/manifest.json`	Voice list `{ id, edgeName, label, gender }[]`. Written by the generator, imported by `audio-manifest.js`.
`scripts/generate-audio.py`	One-shot Python script: discovers every `vi-*` edge-tts voice, generates 92 clips per voice, writes manifest. Run after voice/wording changes.

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, masterMode, autoCallEnabled, autoCallSpeed, emptyCellColor }`.

loto_master_card_* keys are no longer written (host's own player card removed) but old saved data is left untouched.

Component Hierarchy

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.
