+# Central release-please hub for the whole org.
+#
+# One place cuts releases for every repo that carries a release-please config —
+# no per-repo workflow files. Required-workflow rulesets can't host this (they
+# run on pull_request/merge_group only, never push), so instead of forcing a
+# per-repo workflow this runs the release-please CLI against each repo via
+# --repo-url using an org App token. Repos opt in by adding
+# release-please-config.json + .release-please-manifest.json to their default
+# branch.
+#
+# Org App creds live ONLY here: app id in the GH_ACTION_RELEASE_PLEASE_APP_ID
+# org variable, private key in the GH_ACTION_RELEASE_PLEASE_PRIVATE_KEY org
+# secret. The App must be installed on the org with Contents + Pull requests
+# write. Action refs are digest-pinned to their current-latest releases.
