"""453 B05 평면 편집 — 집기 한 판정 · 손잡이 끌기 · 막힌 걸음 놓음 · 스냅만 바꾼 초안.

못박는 것
  - 433-14 ③ · 433-21 ③ 노드 가운데 6 px = 노드 · 밖 = 마커 · 노드 · 손잡이 중 가까운 것 · 맴돔 커서 같은 판정.
  - 433-14 ① 막힌 걸음만 하고 놓으면 미리보기 맞춤을 누르기 전 자리로(맞추지 않은 기준 13/13 → 0).
  - 433-14 ② 스냅 · 분석 지형만 바꾼 뒤 노선이 처음으로 돌아가도 다리 초안 있음(null 아님).
  - 433-21 ① 손잡이 끌기 훑기는 `test_390_5_snap_step_ops`.

짝: `helper_453_plan_pick_draft.cjs`(진짜 TS `_Input` · `_History` · `_Draft` · `StationFit`).
