"""OpenEnv FastAPI application entry point.

This is the file the hackathon judges' OpenEnv client (and any other
EnvClient consumer) will talk to. It builds a FastAPI app via
:func:`openenv.core.create_app`, which wires up:

* ``/health`` — liveness check.
* ``/reset`` — start a new episode.
* ``/step`` — apply an action.
* ``/state`` — inspect current episode state.
* ``/schema`` — JSON schemas for action / observation / state.
* ``/metadata`` — environment metadata (name, description, version).
* WebSocket ``/ws`` — interactive session protocol.
* (Optional) ``/web`` — Gradio debug UI when ``ENABLE_WEB_INTERFACE=true``.

Run with::

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

Or via the Docker default ``CMD``::

    docker build -t hospital-env .
    docker run --rm -p 8000:8000 hospital-env

Override the scenario per container by setting the
``HOSPITAL_SCENARIO`` env var (one of ``normal_day``, ``surge``,
``mass_casualty``, ``night_shift``, ``ventilator_crisis``)::

    docker run --rm -p 8000:8000 -e HOSPITAL_SCENARIO=surge hospital-env
