Implement a custom SSO login and signup flow using Authlib (Python OAuth 2.0 / OIDC library) with FastAPI on the backend and React on the frontend. Users will authenticate via a standard OIDC flow. Sessions will be stored in SQLite. The architecture is provider-agnostic, so adding Google or GitHub login later requires only a new provider config — no restructuring.
