# No trigger-level `paths:` filter, deliberately. A workflow skipped by one
# reports no conclusion at all, and a required check that never reports leaves
# a pull request unable to enter a merge queue and a merge group unable to
# leave it. `merge_group` cannot carry a `paths:` filter in the first place.
# The filter lives in the `changes` job below instead, and `frontend-gate`
# reports the single conclusion the queue waits on. See docs/ci-merge-queue.md.
