 ## Notes
 - Traefik terminates TLS and routes frontend, API, admin, static, media, Grafana, Prometheus, and Uptime Kuma.
+- The frontend is a Next.js standalone Node runtime behind Traefik on internal port `3000`.
 - Alertmanager has been removed from this stack. Prometheus scraping and Grafana provisioning remain intact.
 - Dockerfiles live only in this deployment repository, and compose is intentionally wired only for the nested production layout.
