 2. Dashboard job: install dependencies in `admin-dashboard`, run lint/build.
 3. Deploy job: on `main`, trigger Coolify webhook (optionally authenticated with token).
+4. In two-resource production setup, deploy webhooks can independently trigger backend and dashboard resources.

 ## Deployment Risks and Mitigations

   Mitigation: dashboard re-auth flow and short-lived session design.
 - Risk: DB connectivity interruptions.
   Mitigation: startup validation + retry behavior on mileage writes.
+- Risk: edge proxy misroutes dashboard/API traffic.
+  Mitigation: verify upstream hostnames/ports and health checks after deploy.
