"""354-1 → 392-2 유토곡선 판 = 10-14 판(9edaec82e) 되살림(요구 242-10).

- 유토곡선 = 종단 칸(bodyWrap) 바닥 덮는 판(absolute · z5) · 자기 판(종단 열 아래 칸) 지움.
- 메인 판 끌기 = 종단 · 유토 · 표 세 영역 같은 비율 · 놓을 때 유토 · 표 높이 확정(commitHeight).
- 유토 손잡이 = 판 위 경계 밖(bottom = 판 높이) · 표 손잡이와 ±44 px 나란히 · 접기 = 숨김.
- 표 판 = 열린 유토 위에 쌓임(setBottomOffset).
- 남김 = 유토 [창 분할](판 안 좌상단 = 펼친 때만 보임) · 367-1 늘 전체 맞춤 · 325-2 뿌리 안 판정.
