# Auth Slice
This slice owns sign-in UI and session lifecycle.
- `application/session_controller.dart`: async auth session state.
- `presentation/sign_in_view.dart`: sign-in form and environment status UI.
Touch this slice when you change auth UX, local session behavior, or backend
sign-in integration.

# Auth Application
This layer coordinates auth state and session lifecycle. Start here when you
need to change how the app decides whether a user is signed in.

# Auth Presentation
Auth UI belongs here. Keep sign-in screens, auth-specific widgets, and small
view helpers in this folder rather than mixing them into app bootstrap code.
