 * 일위대가 참조 줄 모달(51-14) — 서고 원본(50-3)을 그 자리에서 고침 · [저장] = 서고 저장 길(`saveTemplate`) ·
 * 그 문서를 쓰는 모든 구조물에 따라감(머리 한 줄 알림) · 그 층을 못 고치면 읽기만.
 *  · 단가승격 [옵션] = 승격 문서 로직 한 줄의 넣을 값 모달(`Labor_Input`)
 *  · 일위조합 [수정] = 사전조합 상세(서고 모드 표 · 안 줄 [옵션] · 수량 · 위로 · 아래로 · 삭제 · 추가)
 * 닫으면(저장 · 취소 모두) `closed` — 부르는 쪽이 구조물 일위대가 표를 다시 셈.
