"""FastAPI application factory for the RAGAS evaluation console.

The app mounts three JSON API routers and serves the single-page static
|
|
frontend. It imports rag_eval only lazily (inside the task manager worker), so
|

the server starts even when the evaluation dependencies are not yet installed.
