  # `main` only. Matching every branch here would double every PR's CI:
  # pushing to a PR branch fires BOTH the push event and the pull_request
  # event for the same commit, running each job twice for an identical
  # result. The pull_request trigger below already covers branches.
  #
  # This run is still worth keeping for main itself - it is post-merge
  # validation against the real merge commit, which is exactly what caught
  # the flaky staleness boundary test in #32 (green on the PR, red on the
  # merge).
