 * 일위대가 불러오기 마법사 ② 단가산출 칸(PLAN 778-5 D-5 · 요구 621 · 622 · 623 · 624) — 모두 줄로만 · 자동 없음.
 *  · 열면 서버 줄 판정(`POST …/sangeun` 빈 확인 = 안 만듦 · D-3) → 블록 표: 단산N · 이름 · 판정(「옮길 수 있음」 ·
 *    「고를 줄 n」 — 캐시 고름 겹침) · 우리 금액 · 엑셀 금액(참고) · 근거 꼬리표(가까운 기초 이름 · 참고) · 만든 SK ·
 *    [확인] 칩(고를 줄 0 일 때만 켜짐) · [줄] 펼침 = 줄 표(`Hopyo_SkLines`) · [보기] = 엑셀 보기 그 블록 첫 행
 *  · 고름 · 확인 = 캐시 `m02-hopyo-sk:{층}:{주인}:{키}`(`SkPick` 꼴) — 누를 때 서버에 안 감 · 자동 저장 없음
 *  · [확인한 것 옮기기 (n)] = 몸 `{확인: [{번, 고름}]}` → 서버가 M01 지금 값으로 다시 셈 · 단위 SK(확인 안 한 블록 안 만듦) ·
 *    만든 블록은 확인에서 뺌 · 못만듦 = 띠(까닭 그대로) · 「모두 확인」 단추 없음
 *  · `count()` = 아직 안 옮긴 블록 · 그중 일위대가 밖 · 고를 줄(마법사 [끝내기] 글)
 *  · 780-2(요구 627) — 부름 칸(「일위대가 n 곳」 · 「일위대가 밖」) · 거르기(전체 · 안 · 밖 · 고를 줄 있음) ·
 *    좁은 꼴(`narrow` = 엑셀 보기 오른쪽 · 칸 여섯 · 블록 줄 누름 = `onRow` · `mark(번)` 강조) · `readOnly` = 옮기기 숨김 ·
 *    두 벌 맞춤 = 알림 `SK_SYNC`(같은 캐시 열쇠 · 고름 바뀜 → 다시 그림 · 옮김 → 받은 판정 그대로) · 옮김 뒤 `HOPYO_BUILT`
