 Enable `ingress.enabled` and set `ingress.host` (and optional TLS). Traffic is sent to Service **`revproxy`** (internal nginx). On k3s, `ingress.className: traefik` matches the default controller.
 
+For **cert-manager**, set `ingress.tls: true`, `ingress.tlsSecretName`, and `ingress.certManager.clusterIssuer` (e.g. `letsencrypt-prod`). Ensure a **DNS A/CNAME** for `ingress.host` points to your ingress before the ACME challenge runs.

 - **Edge proxy stack** (`app/proxy/docker-compose.yml`, host 80/443 Swarm mode) — replaced for K8s by this **Ingress** + `revproxy`; optional **cert-manager** for TLS at the Ingress.
