"""면적산출 범위 → 도면 표(PLAN 41-3 · `M02_MasterTemplete_AreaToDrawing.ts`) — Node 로 TS 를 돌려 판정.

못박는 것
  - 면적 상세 [도면으로 보내기] = 고칠 수 있는 층만(읽기 · 프로젝트 층 단추 0).
  - 보냄 → 표 변환 길(POST …/area/{열}/table) → 같은 열 도면 상세를 엶 → placeTable(style.연결 = T번호).
  - 다른 열 도면이면 안 놓음 · 기존 기록 · 표지와 안 겹치는 id(T1 이 있으면 T2).
  - [저장] 문서 `연결표` = 도면에 남은 표만(지운 표는 빠짐) · 값 = 그 표 칸 글 · 기록 없던 도면은 칸 안 만듦.
  - 다시 열 때 지금 면적 값 ≠ 마지막 값이면 알림 + [업데이트] → updateTable(id, 칸).
