 * 가져온 식 단가산출 모달 머리 판(PLAN 793-3b · 요구 646 · 647 · 652) — `Hopyo_Imported` 가 엶 · 시트(`Sangeun_Detail`) 위.
 *  · 줄 1 = 「새」 · 원본(파일 · 시트 · 행) · 검산 표지(같음 / 다름 n · 줄마다 까닭) · 단가 기준 [우리 단가로] / [엑셀 단가로] ·
 *    바꾸기 전후 금액 · [원본 글 보기]
 *  · 줄 2 = 이음 없는 자원 = 표지 + [이음 고르기]
 *  · 줄 2-2 = 소요량 · 계수 이음(797-2 · 후보 집계 + [이음 보기] → `Hopyo_QtyLinks` 모달)
 *  · 줄 3 = 근거 제안 세 단(확정 · 근접(차이 · 까닭) · 사람 고름 · 793-3a) — 후보마다 [우리 기초로 바꾸기] · [기초 고르기]
 *  · 우리 기초로 바꾼 뒤 = 전후 차이 띠 · 「입력 필요」 붉은 칸(채우기 전엔 그 줄 확인 · 옮김 막힘)
 * 부품 = 단추 · 배지 · 글 · 입력 · 띠 · 표 · 모달(날 단추 · 입력 없음) · 서버 길은 부르는 쪽.
