   17. KANBAN COMPACT — 카드 인덱스 서랍 스타일 겹침 모드
   카드가 실제로 겹쳐 쌓여 보이는 파일 서랍(filing cabinet) 효과.
   --compact-idx CSS 변수(ERB 인라인)로 인덱스 기반 깊이감 제어.
   DnD 호환: 카드는 [data-kanban-list]의 직접 자식 유지.
   ================================================================ */

/* ── 컴팩트 카드: 파일 서랍 스택 ── */
/*
   핵심 원리:
   - 카드 높이를 줄이지 않음 — 실제 카드 내용을 max-height로 잘라 보여줌
   - 탭 대신 실제 카드 상단(제목·태그 등)이 노출됨
   - 큰 negative margin(-48px)으로 다음 카드가 위에 겹침
   - 마지막 카드는 ERB에서 compact: false로 전체 표시
   - 결과: 카드가 실제로 쌓여 있고, 위에서 살짝 보이는 파일 서랍 효과
