-## Project Overview
-
-Classworks (作业板) is a homework board widget for classroom large screens. It's a Vue 3 + Vuetify 3 PWA with real-time sync via Socket.IO. The UI is in Chinese.
-
-## Commands
-
-```bash
-pnpm install          # Install dependencies
-pnpm run dev          # Dev server at localhost:3031 (network-accessible)
-pnpm run build        # Production build (auto-runs prebuild to regenerate sound list)
-pnpm run preview      # Preview production build
-pnpm run lint         # ESLint with auto-fix
-```
-
-## Tech Stack
-
-- **Framework**: Vue 3 (Composition API + Options API mixed), JavaScript (no TypeScript)
-- **UI**: Vuetify 3 (Material Design 3), `@mdi/font` icons, SCSS
-- **State**: Pinia 3
-- **Routing**: Vue Router 4 with file-based routes (`unplugin-vue-router` + `vite-plugin-vue-layouts`)
-- **Build**: Vite 5, pnpm
-- **Real-time**: Socket.IO client (singleton in `src/utils/socketClient.js`)
-- **Data**: Pluggable KV provider abstraction (`src/utils/dataProvider.js`) with IndexedDB local and HTTP server backends
-- **PWA**: `vite-plugin-pwa` with Workbox service worker
-
-## Architecture
-
-### Data Layer
-
-`src/utils/dataProvider.js` abstracts data operations. It routes to either:
-- `src/utils/providers/kvLocalProvider.js` — IndexedDB via `idb`
-- `src/utils/providers/kvServerProvider.js` — HTTP API via axios
-
-Server failover is handled by `src/utils/serverRotation.js`.
-
-### Real-time Layer
-
-`src/utils/socketClient.js` — Socket.IO singleton with room-based token join/leave for live updates.
-
-### Settings Layer
-
-`src/utils/settings.js` — Comprehensive localStorage-based settings with typed definitions, defaults, and legacy migration. ~600 lines.
-
-### UI Layer
-
-File-based routing: each `.vue` in `src/pages/` becomes a route. Layouts in `src/layouts/`. The main dashboard is `src/pages/index.vue` (78KB — the core view composing homework grid, time card, noise monitor, random picker, exam schedule, etc.).
-
-Components are organized by feature:
-- `src/components/home/` — Home page components
-- `src/components/settings/` — Settings cards
-- `src/components/auth/` — Authentication flow
-- `src/components/attendance/` — Attendance management
-- `src/components/common/` — Shared components
-
-### Key Utilities
-
-- `src/axios/axios.js` — Axios instance with auth interceptors and rate limit handling
-- `src/utils/api.js` — API helpers, namespace info, server rotation
-- `src/utils/visitorId.js` — FingerprintJS device identification
-- `src/utils/soundList.js` — Auto-generated from `public/sounds/` by `scripts/generate-sound-list.js` (runs as `prebuild`)
-
-## Code Style
-
-- 2-space indent, trim trailing whitespace (`.editorconfig`)
-- Path alias: `@/` maps to `src/` (`jsconfig.json`)
-- ESLint flat config (ESLint 9) with Vue recommended rules (`eslint.config.js`)
-- Mixed Composition API and Options API usage
-- No TypeScript
