"""RMI Backend — root entry point.

Minimal — delegates everything to app.factory.create_app().

Per v4.0 §T01 + modern factory pattern:
- main.py is the entry point ONLY
- All composition lives in app/factory.py
- Goal: <30 lines, single import, single uvicorn call

Run: `python -u main.py` (CMD in Dockerfile)
