The GitLab Configuration disclosure was the only .settings-content child without the form-group horizontal gutter, so its bordered box and right-flushed checkbox leaked to the pane edge. The footer action rail was a no-wrap flex with zero slack, clipping Save whenever extra footer content appeared; it now wraps on desktop (mobile scroll rail intact).
