"""288 맹암거 횡단 형상(요구 183-3 · 9).

못박는 것
  - 288-1 맹암거 기준 측점 = 측구 없음 · 노면 = 표준 경사로 지대 낮은 쪽 한 경사
    (물넘이 286 · 287 길 — 서버 `tilt_ranges` · `tilt_args` · TS 짝 `tilted` · 암거 경사는
    노면에 안 감 371-3) · 제원 얹기 서버 `attach_underdrains` ↔ TS `attachUnderdrainSpecs`
    같은 값 · 형상 = 노면을 암거 높이만큼 아래로 옵셋 → 성토 쪽은 성토 사면과 만남 ·
    절토 쪽은 절토 사면을 늘여 만남 · 그 안 돌 무늬 · 높이 비면 안 그림.
  - 371-3 암거 경사 = 형상 하단 경계 — 높은 쪽 노면 끝 − 높이에서 암거 경사로 낮은 쪽으로 내림.
  - 288-2 맹암거 형상 누름 = 그 구조물 id 고름(구조물 목록 창구 · 알약 · 폼 · 측점선 따라옴) · 물넘이와 같은
    판정면(보라 손잡이 아래 · 끌기 = 고름 아님 · 287-5) · 노면공 포장 범위 고름과 따로.

진짜 TS 는 `helper_288_underdrain.cjs` 가 Node 로 돌림. 화면은 사용자 확인.
