"""498-2 노선 바뀐 [저장] 계획고 — 브라우저는 손댐(입력)만 · 서버가 자기 옮김 위에 한 번.

- 브라우저(`B05_Profile_Pipeline_Grade` follow `touch` · `gradeTouch`) — 노선만 끌었으면 손댐 0 ·
  끈 뒤 ▲ = 그 열쇠만 · 끄는 중 ▲ = 그 열쇠 포함 묶음 값 그대로 · 지운 열쇠 = `cleared` ·
  첫 기준 없으면 null(옛 길 · 0 칸 통째).
- 서버(`B06_Section_Router_DesignSave_Route.overlay_edits` · `touched_alignment`) — 손대지 않은 옮김
  열쇠는 서버 측점 그대로 · 고친 · 지운 열쇠 자리(0.006 m 안)만 걷고 손댐 값을 얹음 · 브라우저 측점
  열쇠로 서버 열쇠를 덮지 않음(옛 흠 = 두 쪽 측점이 다르면 어긋난 편집을 지움).
