   반응형 브레이크포인트 정책 (현황 기록 — 2026-08)

   이 파일에는 성격이 다른 반응형 기준이 두 종류 섞여 있다. 둘 다 "모바일"을
   뜻하지만 발동 조건이 달라서, 서로 안 맞물리는 화면(대표적으로 아이패드 세로)이
   생긴다. 수정 전 아래를 먼저 읽을 것.

   [A] @media (max-aspect-ratio:3/4)  — 가로세로비 0.75 이하(세로로 긴 화면)
       기준이 "폭"이 아니라 "화면 모양"이다. 뷰포트 폭은 보지 않는다.
       원본 사이트(첫 커밋)부터 있던 기반 전략이며 max- 8곳 + min- 1곳에서 쓰인다.
       (각 사용처에는 "[A] 세로비 기준" 주석을 달아뒀다. grep 하면 찾을 수 있다.)
         .container       max-width 1040 -> 720px, padding 16 -> 20px
         .brand-img img   큰 로고 120px (min-width:768px와 OR 조건)
         .grid            퀴즈 카드 2열 -> 1열
         .tabs-grid       탭 목록 2열 -> 1열
         .tabs-grid       (min- 조건) 가로일 때 내체표 2열
         .header          헤더 폭 제한 해제 + 패딩 재계산
         .brand-img img   작은 로고 28px (min-width:768px와 OR 조건)
         .grid            gap 16px
         #tabs input      font-size 16px (iOS 입력 시 자동확대 방지)
       주의: 폭이 아닌 비율 기준이라 폰 가로모드(비율 2.1)에서는 데스크톱
       레이아웃(카드 2열)이 나오고, 반대로 창을 세로로 길게 늘리면 폭이 넉넉해도
       1열이 된다. "몇 px부터"라는 답이 존재하지 않는다.

   [B] @media (max-width:720px)  — 뷰포트 폭 720px 이하
       나중에 추가된 폭 기준. 4곳에서 쓰인다.
       (각 사용처에는 "[B] 폭 기준" 주석을 달아뒀다.)
         .board-head      게시판 헤더/검색 축소
         #boardToolbarList 게시판 툴바 세로 전환, PC용 표 숨기고 모바일 카드 목록 표시
         .m-post          모바일 카드 스타일
         .home-extras     홈 위젯 세로 전환 + 순서 재배치 + 폭 100%

   [사각지대 - 홈 위젯은 2026-08-13 해소, 나머지는 유지]
   - (해소) 아이패드 세로와 데스크톱 창 721~815px에서 홈 위젯이 한 줄에도 못 들어가고
     정돈된 세로 스택도 아닌 어중간한 줄바꿈이 되던 문제. flex-wrap:nowrap + flex-shrink로
     "좁아지면 두 위젯이 같이 줄어들되 줄바꿈은 안 함"으로 바꿔서 없앴다.
     결과: 폰(<=720px)만 세로 스택, 그 위는 항상 한 줄.
   - 중요: 아이패드 세로의 컨텐츠 폭은 기기와 무관하게 **일괄 680px**이다.
     [A]가 .container를 720px로 캡하고 padding 20px를 주기 때문(뷰포트 744든 1024든 동일).
     "뷰포트 - 패딩"으로 계산하면 틀린다.
   - (유지) [A]는 비율 기준이라 폰 가로모드에서는 화면이 좁아도 데스크톱 레이아웃이 나온다.
     카드/탭 열수가 이에 해당. 폰 가로모드 사용 빈도가 낮아 수용 중.

   [참고] 전체 폭이 넓은 모니터에서 가운데만 차는 것은 위 두 규칙과 무관하다.
   .container의 max-width:1040px + margin:0 auto 때문이며 의도된 설계다(좌우 광고 영역).
