+# Builds the hosted-gateway image for the homelab instance and pushes it to this
+# Gitea's own registry. Deliberately build-only: the GitHub workflow this
+# replaces also SSHed into the Hostinger VPS and redeployed it, which is the
+# machine being retired. Here the image is deployed the way everything else in
+# the homelab is -- a PR bumping the tag in ffaerber/homelab's docker-compose.yml
+# -- so a deploy is a reviewed commit rather than a side effect of a push.
