MONGO_URI=your_mongodb_connection_string
JWT_SECRET=your_jwt_secret
GITHUB_TOKEN=your_github_personal_access_token

Notes

• Credentials are loaded via .env (gitignored) using dotenv
• Port defaults to 5001 locally (port 5000 is reserved by macOS AirPlay Receiver)
• The server uses ES modules ("type": "module") — Node.js v18+ required for native fetch support
