## Overview

1. **Overall shape**
This repository is a **client-only React SPA** for a live multiplayer trivia game. It does not contain the game server; instead, it acts as the browser-facing presentation and interaction layer for a separate backend that exposes **REST APIs** and **STOMP/WebSocket** channels.

2. **App bootstrap**
`src/main.jsx` is the entry point that mounts the app into `index.html`. `src/App.jsx` is the top-level composition layer: it likely defines the route map, common layout, and which pages are public vs protected.

3. **Page-level boundaries**
The app is split into feature pages under `src/pages/`:
- `LoginPage.jsx` / `RegisterPage.jsx` handle authentication entry.
- `DashboardPage.jsx` is the authenticated landing area.
- `LobbyPage.jsx` covers room discovery, joining, and matchmaking.
- `GamePage.jsx` is the live trivia runtime.
- `LeaderboardPage.jsx` and `ClansPage.jsx` are social/competitive views.
This separation is useful for diagramming distinct user journeys.

4. **Authentication subsystem**
`src/context/AuthContext.jsx` is the main state boundary for user identity and session state. It centralizes login/logout/guest handling and exposes auth state to the rest of the app. `src/components/ProtectedRoute.jsx` enforces access control around authenticated routes, keeping unauthenticated users out of game and dashboard flows.

5. **REST API boundary**
`src/api/client.js` is the HTTP integration layer. It wraps Axios and is the place where token-aware request configuration and backend endpoint calls are concentrated. In the architecture diagram, this is the synchronous request path between UI actions and backend persistence/state retrieval.

6. **Realtime game boundary**
`src/hooks/useGameSocket.js` encapsulates the live connection to the game backend via **SockJS + STOMP**. This is the critical low-latency subsystem used for lobby updates, question state, timers, reactions/emotes, and in-game events. It separates connection lifecycle from page components so the live transport can be reused across screens.

7. **Game data flow**
The main live flow is: user enters lobby → socket subscribes/updates room state → game starts → `GamePage` consumes streamed events for timer, answers, score changes, and recovery state. The README indicates state recovery after refresh/disconnect, so the socket layer likely rehydrates from server state instead of relying only on in-memory React state.

8. **Shared UI layer**
`src/components/Navbar.jsx` and `src/components/AnimatedBackground.jsx` are cross-page shell components. The navbar provides global navigation and status display, while the animated background is a decorative layer used to keep the app visually consistent across screens.

9. **Rendering and interaction model**
The UI is mostly driven by page-local React state plus context/hook-based shared state. The design emphasizes smooth transitions and live feedback: timers, lobby polling, reactions, and power-ups are all interactive, stateful UI behaviors rather than static screens.

10. **Styling and presentation**
`src/index.css` and `src/App.css` provide the app’s global styling and visual system. The README describes a dark, glassmorphism-style interface with animation effects, and the repo structure suggests styling is handled through a mix of global CSS and utility-driven classes rather than a complex component library.

11. **External dependencies that matter architecturally**
The key external runtime dependencies are **React/Vite** for the SPA shell, **Axios** for REST calls, and **SockJS/STOMP** for realtime transport. The app also depends on browser storage for persisted auth/session tokens, which means session continuity is client-managed between page loads.

12. **Important diagram boundaries**
For an architecture diagram, the main boundaries are:
- Browser SPA shell
- Auth/session context
- REST API client
- Realtime WebSocket/STOMP channel
- Feature pages for lobby/game/social views
- Shared layout/visual components
That set captures the main control flow without over-modeling the UI details.
