tiennm99 19e10fd1ce feat(master): circular token style with pink/green ring per value range

Replaces the orange/red filled-square cells on the master tracking
board with a circular token treatment inspired by the Hội chợ "Các
số đã ra" panel. Each numbered cell now renders a centered circle
with a colored ring — pink for 1–49, green for 50–90 — over a
cream-yellow fill when the number has been called, or dimmed/empty
when it has not. The most recent draw keeps its red accent via a
ring-offset highlight + slight scale, so the host can still find
"vừa xổ" at a glance. Draw-order superscript stays at the cell's
top-right corner, now in muted slate (visible against both the
cream-filled and dim-empty token states).

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: 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.
