+Backend README
+
+This is a minimal scaffold for the LifeRPG backend. It currently ships a tiny stdlib-based HTTP JSON endpoint for local development.
+
+Next steps:
+- Replace with FastAPI + Uvicorn for production.
+- Add ORM (SQLAlchemy/Alembic) and migrations.
+- Add OAuth2 and integration adapters.
+
+Run (dev):
+
+python server.py
