Match the BAMBOORAFT physical sheet: - Cell aspect changed from square to 3:5 (taller than wide), matching the printed paper proportions - Number cells rendered with .tan-tan-num: condensed system-font stack (Arial Narrow / Avenir Next Condensed / Roboto Condensed), font-weight 900, negative letter-spacing for tight fall-back on platforms without a true condensed face. Sized text-2xl / sm:text-3xl to fill the taller cells. Black number on white cell. - Default empty-cell color flipped from Minh Tân brown (#7a4a2b) to BAMBOORAFT blue (#1e88e5). Settings store + test updated. Users who picked a different color in settings keep their choice. - Section dividers and labels recolored from orange to matching blue. - Section labels relabelled to the BAMBOORAFT trio: "Tân Tân" / "An khang thịnh vượng" / "Tân Tân tốt nhất"

# 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 circular tokens (pink ring for 1–49, green for 50–90; cream fill when called, dim when uncalled; red ring + scale on last-called) and 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: Tân Tân / An khang thịnh vượng / Tân Tân tốt nhất). Tall (3:5) cells with condensed bold black numbers (`tan-tan-num` font stack), white number cells, blue empty cells. 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. |
