"""RMI Backend — router mounting.
Single source of truth for every router. Adding a new domain:
1. Create the module with a `router = APIRouter(...)` attribute
2. Add the import path to ROUTER_MODULES below
3. Done — factory.create_app() picks it up automatically
Per v4.0 §T01 + ADR-0001, this replaces the hardcoded lists that
existed in the old main.py. Each mount is isolated — one failure
doesn't break the others.
