"""345-4 노선 추천 → 좌측 새 칸 「노선 추천」(지운 「계획노선」 자리) — [노선 추천] · 현재 추천 · [초기화].

· 칸 요소는 `_Panel_Recommend` 가 만들고 편집기(`_RouteEdit_Initial`)가 밖에서 받아 건다
· 추천 창은 공용 모달 하나 · [적용] = 본문 평면에 되돌리기 한 칸(`restoreSnapshot(…, true)` → 이력 한 걸음)
· 추천 창의 「지금 노선」은 본문 편집기 지금 노드
칸 생김새 · 차례는 `test_design_view_parity` · `test_311_panel_folded` 가 봄(화면 확인은 브레인).
