+# backend/serve.py — Launches FastAPI + Socket.IO API server (Milestone 6)
+# Run with:  uvicorn serve:socket_app --host 0.0.0.0 --port 8000 --reload
+#
+# This module:
+#  1. Initialises the database (creates tables if missing)
+#  2. Exports `socket_app` — the combined FastAPI + Socket.IO ASGI app
+#     that uvicorn (or any ASGI server) can run directly.
+#
+# The Telegram bot runner (run.py) remains a separate process.
