 * B09_Estimation_UI_Detail.ts
 * 호표 본표(일위대가표·단가산출근거·시간당 중기) 한 장 + **들어가기 자취** (PLAN 12장 1차)
 *
 *   - ⭐ STmate 를 익숙하게 만드는 동작 = 타고 들어가기(브레인 판정). 내역 줄 → 제 N 호표 →
 *     호표 안 줄(일위대가·단산·중기) → … 을 누를 때마다 자취가 쌓이고, 자취 글을 누르면 그 자리로 되돌아감.
 *   - 표 모양은 실무 `일위대가표`·`단가산출근거` 시트: 명칭·규격·수량·단위 · 합계/노무/재료/경비(단가·금액) · 비고.
 *   - ⚠ 합계 줄은 서버 값(호표 성분 소계 원 미만 절사) — 여기서 안 더함.
