"""FastAPI application for the Ontology Architect Environment.

This module exposes the research environment over HTTP, making it compatible
with HTTPEnvClient.

Usage:
    # Development (with auto-reload):
    uvicorn server.app:app --reload --host 0.0.0.0 --port 8000

    # Production:
    uvicorn server.app:app --host 0.0.0.0 --port 8000 --workers 4

    # Or run directly:
    python -m server.app

    Entry point for direct execution via uv run or python -m.

    This function enables running the server without Docker:
        uv run --project . server
