"""626-3 B05 평면 예정노선 그리기 → 다시 추적 → 편집기 한 걸음 → [저장](요구 530 · 531 · 결정 D3 · D4 · D9 · D10).

- 셈(TS `logic/B05_Profile_ExpectedDraw.ts` · tsc 로 옮겨 Node) — 구간 다시 긋기 갈음(앞뒤 그대로 · 거꾸로 그음 뒤집음 ·
  시점 · 종점 자리) · 다음 점 방식 넷(D03 셈 그대로) · 선 위 자리 · 첫 구간 정방향 앞 점.
- 지킴(글 대조) — 다시 추적 = `/route/follow` 만(저장 0) · `/route/replan` · `as_initial` · `expected_route.csv` 안 부름 ·
  결과 = 편집기 `restoreSnapshot(…, true)` 한 걸음 · [저장] = 손 편집 같은 길(`bindRouteApply`) + 초안 `expected` ·
  걸음 사진 · 노선 초안에 고친 예정노선 실림(되돌리기 · 세션 되살림) · 같은 선 판정에 예정노선 · 긋기 방식 칸 공용 ·
  판 켜면 캔버스 누름을 먼저 받음(재기 · 계획선 고르기 막음) · RouteEdit 700 줄 안.
