+# Build + push the API and web container images to the git.mancinas.io registry.
+#
+# Two images from this one repo:
+#   git.mancinas.io/rmancinas/jorgecuadros-api
+#   git.mancinas.io/rmancinas/jorgecuadros-web
+#
+# Comprehensive versioning (docker/metadata-action). Every build pushes a set
+# of tags so an image is addressable at several granularities:
+#   - vX.Y.Z / vX.Y      when the trigger is a git tag  vX.Y.Z   (releases)
+#   - <branch>           the branch that was pushed (e.g. master, feat-foo)
+#   - sha-<short>        immutable per-commit id, always present
+#   - latest             only on the default branch (master)
+# The same version string + commit + build date are baked into the image as
+# ARG/ENV (APP_VERSION / GIT_SHA / BUILD_DATE) and as OCI labels, so a running
+# container can report exactly what is deployed.
+#
+# Release flow:  git tag v1.2.0 && git push origin v1.2.0  -> versioned images.
