            This issue has had no activity for 30 days, so it is marked stale.
            It will be closed in 3 days unless there is new activity. Comment
            if it still matters and it stays open.
          close-issue-message: >
            Closed after 3 more days without activity. Reopen it, or open a
            new issue, if it still matters.
