- User model (users table) with bcrypt password hashing - JWT-based login API (POST /api/auth/login, GET /api/auth/me) - Default admin account (admin/admin123) auto-created on startup - Login page with centered dark-themed login card - Route guards + Axios interceptors for token management - Login page renders without sidebar (standalone layout) - Gunicorn --preload to avoid worker DDL race condition
