.env.example

```plaintext
# Backend Configuration
OPENAI_API_KEY=your_openai_key_here
DEEPSEEK_API_KEY=your_deepseek_key_here
USE_GPU=true  # Set to false for CPU-only mode
MAX_CONCURRENT_TRANSCRIPTIONS=3
CACHE_TTL_MINUTES=60

# Frontend Configuration (Vite)
VITE_API_BASE_URL=http://localhost:8000
VITE_DEFAULT_TIMEOUT_MS=30000

# Security
JWT_SECRET=your_jwt_secret_here
JWT_EXPIRE_MINUTES=30

# Redis (for caching)
REDIS_URL=redis://localhost:6379

# Storage
STORAGE_TYPE=local  # or 's3'
S3_BUCKET_NAME=your-bucket-name
S3_ACCESS_KEY=your-key
S3_SECRET_KEY=your-secret
```

Now let me generate the client and server folders. Would you like me to proceed with those next? I'll need to send them in separate responses due to size constraints. The complete structure will include:

1. `/client` - Vite/React frontend
2. `/server` - FastAPI backend
3. Deployment files
4. Docker configuration

Would you like me to continue with any specific part first?
