## Context
{{task-context}}

## Requirements

### Core Features
**Live Quiz System**
- Room code entry for instant participation
- Timed multiple-choice questions with real-time scoring
- Live leaderboard updates throughout sessions

**Personal Whiteboard**
- Local-only canvas for individual problem solving (not shared with others)
- Tools: pen, eraser, undo
- Integrated directly into the quiz flow

### UX Design
- Split-screen layout: question display (top half), whiteboard (bottom half)
- Swipe-up gesture expands whiteboard to full screen
- Minimalist interface to reduce cognitive load and maintain focus

### Technical Architecture
- Real-time communication via Firebase or WebSocket
- Backend responsibilities: room management, question distribution, answer validation, score calculation
- Client-side whiteboard rendering (no server sync required)

### MVP Scope
Include only:
- Live quiz participation (student view)
- Personal whiteboard functionality
- Real-time leaderboard

Exclude: teacher dashboard, shared boards, session creation UI

### Competitive Positioning
- **vs. Kahoot**: Personal whiteboard enables deeper problem-solving; no host required for student practice
- **Target audience**: University students using the app for exam preparation and concept reinforcement

## Output
Provide a comprehensive design specification covering user flows, screen layouts, technical requirements, and implementation priorities. Ensure the design is scalable, intuitive, and supports an engaging educational experience.
