## Appendix

### A. Authentication Flow Diagram

```
Registration Flow:
User → Frontend (Registration Form) → API (RegisterUserCommand)
  → Domain (User.Create) → Database → Response (User Created)

Login Flow:
User → Frontend (Login Form) → API (LoginCommand)
  → Verify Password → Generate JWT Token → Response (Token)
  → Frontend (Store Token) → API (Subsequent Requests with Bearer Token)

Protected API Request:
User → Frontend (With Token) → API (JWT Middleware validates token)
  → Authorized → Controller → Response
```
