tiennm99 839afd9201 feat(settings): empty-cell color picker with persisted store

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.

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" }`.

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.
`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.
