   펼침 동작에 대하여  (2026-10 재수정)
   ---------------------------------------------------------
   높이를 애니메이션하지 않습니다. 높이는 한 번에 바뀌고,
   안쪽 카드만 서서히 나타납니다.

   [왜 이렇게 했나]
   높이가 조금씩 자라는 방식은, 자라는 매 순간마다 브라우저가
   그 아래에 있는 구축사례·숫자·문의 영역과 푸터까지 전부
   다시 계산하고 다시 그립니다. 0.24초 동안 열 몇 번을 반복하는 셈이라,
   그래픽 성능이 넉넉하지 않은 PC 에서는 이 계산이 제때 끝나지 않아
   느린 화면처럼 보입니다. 앞서 두 번(높이 측정 제거, 시간 단축)은
   이 계산 자체를 없애지는 못했습니다.

   지금 방식은 높이 계산이 클릭당 한 번뿐입니다.
   카드가 나타나는 효과는 투명도와 위치 이동만 쓰는데,
   이 둘은 화면을 다시 계산하지 않고 그래픽 카드가 바로 처리합니다.
   그래서 어떤 PC 에서도 끊길 수 없는 구조입니다.

   [되돌리고 싶다면]
   .sol-pn 에 transition:grid-template-rows .24s 한 줄을 넣으면
   예전처럼 높이가 스르륵 자라는 방식이 됩니다.
