===========================

FastAPI application built with openenv-core's create_app().
Exposes /reset, /step, /state, /schema, /ws endpoints.

Usage:
    uvicorn server.app:app --host 0.0.0.0 --port 7860

HuggingFace Spaces:
    The openenv.yaml points to this file as the app entry point.
    HF Spaces runs on port 7860 by default.
