## 🛠️ Setup
### Prerequisites
- Node.js 18+
- Vercel account with Postgres storage
### Local Development
```bash
npm install
# Create .env.local with:
# POSTGRES_PRISMA_URL=your_postgres_url
# POSTGRES_URL_NON_POOLING=your_direct_url
# JWT_SECRET=your_secret
npx prisma db push # Create tables
npx prisma db seed # Seed 30 quiz questions
npm run dev # Start at localhost:3000
```
### Deploy to Vercel
1. Push to GitHub
2. Import project in Vercel
3. Add Vercel Postgres from Storage tab
4. Add `JWT_SECRET` environment variable
5. Deploy — Prisma generates automatically via `postinstall`
