+Crisis Bridge — HTTP integration between the-door web and hermes-agent.
+
+Provides:
+- GET /api/crisis/escalations    — list recent escalation events
+- GET /api/crisis/stats           — aggregate statistics
+- POST /api/crisis/log            — log a new escalation (from hermes-agent)
+- POST /api/crisis/resolve/:id    — mark escalation as resolved
+
+Can be mounted as an ASGI/FastAPI sub-app or used standalone.
+Falls back to a simple HTTP server if no framework is available.
