- types/ground.ts: 위치 (육상·하상·해상), 지하수위 고려 and EL, 지층 행
(name and 하단 EL, from the top down). Checks G01 (layer order), G02 (water
level range), G03 (layer name).
- The 지반고 still feeds the soil cover check; the layer rows and water level
are inputs and do not change the 3D model.
- view/ground-svg.ts: the 삽도 drawn from the inputs and the generated
footings and piles on one EL scale.
- 일괄 적용 copies 위치 and 지하수위 to the checked piers (속성 복사 item,
off by default). Changes list shows arrays and booleans as text.
