-#   • This file is a THIN CALLER STUB. All rebase/merge serialization logic
-#     lives in the reusable workflow above.
-#   • You MAY change: the ref in the `uses:` line when upgrading the reusable
-#     workflow version (bump to latest commit SHA or tag of petry-projects/.github).
-#   • You MUST NOT change: the concurrency group name, the explicit secrets
-#     block, or the job-level `permissions:` block — reusable workflows can be
-#     granted no more permissions than the calling job has, so removing the
-#     stanza breaks the reusable's gh API calls. Do not remove either trigger
-#     (`push` keeps the self-sustaining chain; `workflow_dispatch` allows
-#     manual queue flushes).
-#   • If you need different behaviour, open a PR against the reusable in the
-#     central repo.
