   이라서 뷰포트가 약 1300px 아래로 내려가면 520px 에 못 미친다.

   값은 전부 min()/clamp() 로 "카드 폭 520px 기준 픽셀값" 을 상한으로 잡았다.
   → 카드가 520px 이상이면 기존 픽셀값 그대로라 1300px 이상 화면은 변화가 없고,
     그 아래에서만 글자·여백·이미지가 카드 폭에 비례해 줄어든다.

   1024 이하는 카드가 세로로 쌓이는 별도 레이아웃이라 이 블록을 적용하면 안 된다.
   (여기 선택자는 .card.is-focused ... 라 1024 블록의 .card__body 보다 우선순위가 높아
