role

Provides authentication and authorization infrastructure for the API, including OIDC login, session management, and dependency injection for protected routes.

arch

Modular security layer using FastAPI dependency injection pattern, with separation of concerns across cookie handling, OIDC flow, session state, and reusable auth dependencies.
