/* 클로드비서 허브 화면 스타일 (PIN-OPS-012)
   목적: Claude Code 데스크톱 앱의 구조(좌 목록 / 중앙 대화 / 우 패널 / 하단 입력칸)를 축소 차용. 토큰은 자체 정의(외부 로고·워드마크 없음).
   테마: :root = 라이트, [data-theme=dark] = 다크, [data-theme=auto] 는 prefers-color-scheme 를 따른다.
   반응형: <760 모바일(하단 탭 + 서랍 + 시트) / 760～1099 2열 / ≥1100 3열. 폴드8 접힘(≈373px)·펼침(≈800px) 둘 다 이 구간에 든다.
   실패 지점: 없음(정적). 클래스 이름은 app.js 와 1:1 이므로 바꾸면 둘 다 바꾼다. */
