            This pull request has had no activity for 60 days and is being marked as stale.
            It will be closed in another 30 days if no further activity occurs.
            To keep it open, push a new commit or leave a comment.
            Maintainers may apply `pinned`, `status/blocked`, `status/on-hold`,
            or `status/ready-for-merge` to exempt it from auto-close.
          close-pr-message: >-
            This pull request has been closed after 30 additional days of inactivity.
            You are welcome to reopen it or submit a new pull request if the change is still relevant.
            Thanks for contributing!
