+# Contact Mailer - Lightweight email sender for felhom.eu contact form
+# Uses Resend.com API for transactional email delivery.
+#
+# PREREQUISITES:
+#   1. Build and push the container image:
+#      docker build -t contact-mailer:latest .
+#      # Option A: Push to Gitea registry (if configured):
+#      #   docker tag contact-mailer:latest gitea.felhom.eu/felhom/contact-mailer:latest
+#      #   docker push gitea.felhom.eu/felhom/contact-mailer:latest
+#      # Option B: Import directly into k3s (single node):
+#      #   docker save contact-mailer:latest | sudo k3s ctr images import -
+#
+#   2. Create the Secret with your Resend API key:
+#      kubectl create secret generic contact-mailer-config \
+#        --namespace=felhom-system \
+#        --from-literal=RESEND_API_KEY='re_xxxxxxxxxxxx'
+#
+#   3. Apply this manifest:
+#      kubectl apply -f contact-mailer.yaml
+#
+#   4. Test:
+#      # Health check:
+#      curl https://felhom.eu/api/healthz
+#      # Send test email (only works if DEBUG=true):
+#      curl -X POST https://felhom.eu/api/debug/test
+#
+#   5. Update contact form endpoint in kapcsolat.html:
+#      CONFIG.formEndpoint = '/api/contact';
+#
+# DEBUGGING:
+#   kubectl logs -n felhom-system deploy/contact-mailer -f
+#   kubectl exec -it -n felhom-system deploy/contact-mailer -- wget -qO- http://localhost:8080/healthz
