"""755 B05 평면 예정노선 수정 흐름(요구 589-1 · 3 · 5 · 6 · 7 · 8).

- 755-1 켠 동안 = 판만 고침 · 끊김 허용(가운데 묶음 지움) · 이 판 사진첩(Ctrl+Z · 도구줄 단추) ·
  끌 때 한 번 = 끊겼으면 알림하고 안 끔 · 바뀌었으면 `/route/follow` 한 걸음 · [잇기] = B05 사용.
- 755-2 켠 동안 재기 = D03 재기 겹 · 받은 노선 = 분홍 점선 + 검은 테 · 켬 설명 걷음 · 위치 칸 걷음.
- 755-3 켠 채 판 고침 = [저장] · [확정] 막고 알림 · 떠남 = 공용 떠남 물음(탭 닫기 = 브라우저 물음).
