   온톤 — 앱 스타일 (반응형)

   시안 대조
   - PC 시안의 .d-* 조각을 그대로 계승하되 1280 고정폭 → 유동폭으로 바꿨습니다.
   - 모바일 시안의 셸(.a-bar / .a-tabbar / .a-dock)을 같은 파일에 흡수했습니다.

   화면 분기 (PC 우선)
   - 1080px 이상 : 사이드바 + 본문 + 우측 패널. 모든 작업 가능.
   - 720~1079px  : 사이드바가 드로어로 접힘. 우측 패널은 본문 아래로.
   - 719px 이하  : 모바일 셸(상단바 + 하단 탭바). 열람 전용 —
                   시안 선택 · 키트 다운로드 · 고도화 피드백은 잠기고
                   "PC에서 이어서 작업하기"로 넘깁니다.
