/* =============================================================================
 * M02_MasterTemplete_Sangeun_Detail.ts
 * M02 단가산출(SK) 상세(PLAN 717-2b · 요구서 4장 3 · 4 · 13 · 17 · 24) — M01 「단가산출 로직」 상세 부품을 M02 길로.
 *   보기 넷(`LogicLab_View`) = 단가산출 상세(고침 표 · `Sangeun_Cover`) · 인력·재료·경비(공용 계산서 · SK 셈 답) ·
 *   시험 계산(`Logic_Calc` · 바탕 M01 로직) · 텍스트 수식(바탕 M01 로직 식) · 기본정보 = 바탕 로직(맨 위 접힘)
 *   고침 = SK 덮개 · 더한줄(`Sangeun_Pick`) · 뺀줄(꼴 = 서버 `M02_Sangeun_Doc`) · 값 = 서버 셈 길 최신 응답만
 *   시험 입력 = SK 셈 `입력값`(저장 안 함) · [저장] = 화면 문서 → 서버가 다시 셈(원값 · 바탕판)
 *   바탕 없는 SK = [M01 로직 고름] → 바탕 · 단위 · 바탕 없이 줄만도 됨
