+# Packages the chart for a release release-please has already cut, attaches the
+# tarball to that release, and merges one entry into the Helm repository index on
+# gh-pages.
+#
+# This does not use chart-releaser. chart-releaser names its release
+# "{{ .Name }}-{{ .Version }}", which is exactly the graylog-X.Y.Z tag
+# release-please already owns, so it finds the release present and, running with
+# skip_existing, declines to upload anything. The run goes green and no chart
+# ships.
+#
+# release-please.yaml calls this workflow. A tag or release trigger would never
+# fire, because refs created with GITHUB_TOKEN raise no workflow events. Do not
+# turn this into a release-triggered workflow.
