/* 카드 클릭 영역 — anchor → button 교체 시 시각 유지.
   배경/테두리는 wrapper 클래스(.learn-card/.featured-video-card)가 책임지고,
   여기서는 button user-agent의 layout 영향만 무력화 (text-align/font/color 상속 등).
   ⚠️ main.css의 generic `button:hover { background:#0056b3 }` 룰이 있어
   wrapper 클래스의 :hover에 background:#fff를 명시해야 호버 시 파랑이 새지 않음. */
