+# Builds the Docker image and pushes it to Gitea's built-in container registry
+# on every push to main. Tags each build as :latest and :<commit-sha>.
+#
+# PREREQUISITES on your Gitea instance:
+#   1. Actions must be enabled (app.ini: [actions] ENABLED = true) and at least
+#      one act_runner registered.
+#   2. The runner must be able to build images. act_runner needs access to a
+#      Docker daemon — either run the runner with the host Docker socket mounted
+#      (-v /var/run/docker.sock:/var/run/docker.sock) or in docker-in-docker mode.
+#   3. The Package Registry must be enabled (it is by default).
+#
+# TOKEN: the workflow tries the auto-injected GITHUB_TOKEN first. If your Gitea
+# version does not grant it package-write scope, create a Personal Access Token
+# with "write:package" scope and add it as a repository secret named
+# REGISTRY_TOKEN (Repo > Settings > Actions > Secrets).
