Soft visual constraint: no row has cols n, n+1, n+2 all filled. Implementation = constraint-aware per-row picker (uniformly samples triple-free completions of the forced+candidate set) + whole-grid rejection sampling (up to 200 attempts). Hard invariants (5 per row, 5 per col, ascending column values) are never sacrificed; if the soft constraint can't be met, the generator returns the best attempt. - src/lib/game-logic.js: hasThreeInARow, combinations, pickFilledColsOnce, pickFilledCols rejection wrapper - src/lib/game-logic.test.js: 300-trial strict assertion - docs/codebase-summary.md, project-overview-pdr.md: note the rule

# 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. 4 fieldsets: Giao diện (theme auto/light/dark), Chế độ quản trò (master mode toggle), Tự động xổ (auto-call + speed 1–10s), 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/settings-store.svelte.js` | Reactive global UI settings via Svelte 5 runes. Stores 5 keys: `theme` (enum: "auto" / "light" / "dark"), `masterMode` (bool), `autoCallEnabled` (bool), `autoCallSpeed` (1–10), `emptyCellColor` (hex). 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` | 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` | 27 unit tests: defaults, loadSettings (restore 5 keys from localStorage, apply CSS vars, toggle dark class, handle empty/corrupt), saveSettings, resetSettings, theme toggle (auto → OS pref detection), master mode, auto-call + speed, 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). |
|
||
| `static/_redirects` | Cloudflare Pages: `/* / 301` — every unknown path 301-redirects to homepage. Static assets are served first so this only fires on misses. |
|
||
|
||
## 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
|
||
|
||
```
|
||
RootLayout
|
||
└── HomePage (/) ← single page; any other URL redirects to /
|
||
├── PlayerBoard (storagePrefix="loto")
|

├── [if settings.masterMode]
|
||
│ └── MasterPanel (controls, history, 11×9 tracking grid)
|

└── 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. |
