+# RECOMMENDATIONS #2: automated dependency-update PRs (NuGet, npm, Dockerfiles, Actions)
+# that ride the existing required CI gates. Runs weekly + on demand.
+#
+# ONE-TIME SETUP (manual): create a Gitea personal access token with scopes
+# repo (rw) + user (r) + issue (rw) + organization (r), and add it as the Actions
+# secret RENOVATE_TOKEN (repo Settings -> Actions -> Secrets). Without the secret this
+# workflow fails fast with a clear message. See https://docs.renovatebot.com/modules/platform/gitea/
