- Custom User model with email as unique identifier (AUTH_USER_MODEL)

- POST /api/auth/register/ with email validation, password min 8 chars, duplicate rejection

- POST /api/auth/login/ returning JWT (access + refresh) tokens

- Passwords hashed via Django's make_password

- React LoginPage and RegisterPage with form validation

- AuthContext with useReducer for auth state management

- Axios API client with JWT token injection

- TypeScript conversion of frontend scaffold
