Quizflix App Development

You are a senior Mobile App Developer specializing in real-time interactive applications with expertise in multi-user quiz platforms, admin-player architectures, and QR-based session management.

Your task is to design and develop **Quizflix**, a TV show and movie quiz app that supports admin-controlled game sessions with live player connectivity.

## Core Requirements

### Admin Interface (Quiz Host)
- **Quiz Creation Studio**: Form-based editor to create quizzes with:
  - Question text input and multiple-choice answer options
  - Image upload (posters, stills, or custom media)
  - Correct answer designation
  - Quiz metadata (title, category, difficulty)
- **Session Management Dashboard**:
  - Generate unique QR codes per game session
  - Live waiting room showing connected players/teams
  - Manual "Start Game" control to begin when ready
  - Real-time scoreboard view during gameplay

### Player Experience (QR Code Join Flow)
- QR scan → instant session join (no login required)
- Waiting room screen with session info and participant count
- Question display interface with answer selection buttons
- Immediate answer feedback: **"+"** for correct, **"–"** for incorrect
- Post-question results table showing all teams' performance with "+" / "–" symbols per answer

### Technical Architecture
- Real-time data sync between admin and all connected players
- Secure session-based QR authentication (expiring codes, unique per game)
- Responsive UI optimized for mobile screens (both admin and player)
- Low-latency answer submission and scoreboard updates

## Deliverables

Provide a complete technical specification including:

1. **Tech Stack Recommendation**: {{tech-stack}} (specify frontend framework, backend/real-time engine, database, QR library, hosting platform)
2. **Architecture Document**: System design diagram, data flow between admin/players, session lifecycle
3. **Feature Implementation Plan**: Wireframes or screen flows for admin quiz creator, player join flow, question display, and results table
4. **Security & UX Considerations**: QR expiration strategy, connection reliability, offline handling, intuitive navigation patterns
5. **Development Roadmap**: Phased milestones (MVP → beta → production-ready)

## Context

{{app-context}}

## Constraints

- Prioritize **seamless UX**: intuitive navigation, minimal friction in join flow, clear visual feedback
- Admin tools must be **efficient**: fast quiz creation, one-click game start, glanceable scoreboard
- QR system must be **reliable and secure**: handle concurrent sessions, prevent unauthorized joins, graceful reconnection
- Design for **scalability**: support 10–50 concurrent players per session without performance degradation

Focus on production-quality code architecture, not pseudocode. Highlight any third-party services (e.g., Firebase, Socket.io, Pusher) that accelerate development.
