"""
Module: app.py
Purpose: FastAPI server exposing the TriageFlow environment via HTTP/WebSocket.
Part of: Medical Triage Assistant — OpenEnv Round 1
Author: Team Squirrel

Overview:
    Uses OpenEnv's create_app() to automatically create all required
    endpoints: /reset, /step, /state, /health, /ws, /docs, /web.
    This is the entry point when running the server in Docker or locally.

Dependencies:
    - openenv.core.env_server.http_server: create_app
    - models: TriageAction, TriageObservation
    - server.triage_flow_environment: TriageEnvironment

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