"""FastAPI entry point for Red Button v2.

Run locally:

    uvicorn server.app:app --host 0.0.0.0 --port 8000

The Environment *class* (not an instance) is passed to ``create_app``
so ``SUPPORTS_CONCURRENT_SESSIONS = True`` can spawn one fresh
environment per WebSocket session — required for parallel GRPO
rollouts (PROJECT.md §13).
