  #
  # Fork-friendly: upstream stride3d/stride always runs (the repository-name clause covers
  # both direct pushes and fork→upstream PRs, where base-repo `vars` aren't readable from a
  # fork PR's context). On forks, push/PR only run when STRIDE_ENABLE_PUSH_CI is set on the
  # fork. workflow_dispatch always punches through so manual runs work anywhere. Downstream
  # jobs `needs: changes`, so this single guard cascades — no per-job edits needed.
