Adds a gear button + modal on /, /master with a native color picker and 8 preset swatches for the empty-cell background. The selected color repaints both the player card AND the master tracking grid via the --empty-cell-bg CSS variable. Default brown matches the physical Minh Tân paper card. settings-store.svelte.js: Svelte 5 rune-based reactive store, state hydrated on layout mount, persisted to localStorage key loto_settings. Validates hex (#rrggbb regex) before applying — keeps the CSS sink safe and ignores corrupt or shorthand-3-digit payloads. SettingsButton.svelte: gear icon, modal with picker + presets + reset + close, escape-to-close via window keydown listener (the trigger button retains focus on open, so a dialog-scoped handler would miss). eslint.config.mjs: declares Svelte 5 rune globals so .svelte.js stores lint clean. Docs synced: PDR, codebase-summary, system-architecture, roadmap.

# 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 (`/`). Instructions toggle, PlayerBoard component, indigo gradient branding. |
|
||
| `src/routes/master/+page.svelte` | Host page (`/master`). Controls (new game, draw number), 11×9 last-digit-aligned master board with draw-order overlay, host's player card. |
|
||
|
||
### Shared Components
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/PlayerBoard.svelte` | Reusable player card (9×9 grid rendered as 3 stacked 3×9 mini-cards: Minh Tân / Loại đặc biệt / Tấn tài tấn lộc). Handles crossed state, bingo popup, "Chờ X" toast. 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. Color picker + 8 preset swatches for empty-cell color. Reset-to-default button. Mounted on both `/` and `/master` headers. |
|
||
|
||
### Game Logic
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/lib/game-logic.js` | Stateless utilities: generateGrid (constraint-aware picker — exact 5 per row & per col, ascending-sorted columns), saveGrid, loadGrid, saveCrossedState, loadCrossedState, isRowComplete, getWaitingNumber. |
|
||
| `src/lib/settings-store.svelte.js` | Reactive global UI settings via Svelte 5 runes. `emptyCellColor` (hex) persisted to localStorage `loto_settings`. Pushes value to `--empty-cell-bg` CSS var on `:root`. |
|
||
|
||
### Styling
|
||
| File | Purpose |
|
||
|------|---------|
|
||
| `src/app.css` | Root styles: Tailwind @import, CSS variables (light/dark), `.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` | 26 unit tests: generateGrid shape (9×9, 5 per row/col, no duplicates), column ranges & ascending sort, row completion, waiting number detection, persistence (saveGrid/loadGrid/saveCrossedState/loadCrossedState with validators). |
|
||
| `src/lib/settings-store.test.js` | 12 unit tests: defaults, loadSettings (restore from localStorage, apply CSS var, handle empty/corrupt), saveSettings, resetSettings, color validation. |
|
||
|
||
### 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). |
|
||
|
||
## 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_master_card_grid` | Host's player card numbers. |
|
||
| `loto_master_card_crossed` | Host's marked cells. |
|
||
| `loto_settings` | Global UI settings: `{ emptyCellColor: "#rrggbb" }`. |
|
||

## 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. |
|
||
| `buildBoard()` | master/+page.svelte | Builds 11×9 master grid; row = ones-digit, col = tens-digit; col 0 holds 1–9, col 8 holds 80–90. |
|
||
| `handleCellClick()` | PlayerBoard.svelte | Toggle crossed[row][col]. |
|
||
| `saveGrid()` / `loadGrid()` | game-logic.js | localStorage with prefix-based keys. |
