-Viewing logs in Grafana
-- Grafana is available on the port exposed by compose (default `3000`).
-- The Loki datasource is configured to use `http://loki:3100` (see compose). In Grafana Explore choose the Loki datasource and run queries such as:
-
-  - `{job="rad_app"}`  (all collected logs)
-  - `{job="rad_app", filename="/var/log/rad/nginx.access.log"}`
 
 Notes & recommendations
 - In development the `logs/` folder is ignored by git (`/.gitignore` updated). Do not commit runtime logs.

 - If you need nginx to re-resolve the backend service IP without restarting, consider using `resolver` and variable-based upstreams in the nginx config. For many development workflows restarting nginx after web restarts is the simplest approach.
 
 If you want, I can also add a short `docs/OBSERVABILITY.md` with more details and recommended production settings (TLS/auth for Loki, retention, log rotation).
