🌐 URL Patterns

Authentication Endpoints

/login/                              - User login
/logout/                             - User logout

/password-reset-confirm/<uid>/<token>/  - Confirm password reset
/password-change/                    - Change password (authenticated)
/account/                            - User account dashboard (authenticated)
