concurrency:
  # One concurrency group per workflow + ref.
  #
  # - PRs use `refs/pull/<PR_NUMBER>/merge`, so new commits cancel older
  #   in-progress runs for the same PR.
  # - A merge does NOT cancel the PR's own runs: this group is keyed on
  #   refs/pull/<N>/merge and the master push on refs/heads/master, so they
  #   never share a group. See the cancel-pr-runs-on-close workflow.
  # - Branch pushes are isolated by ref.
