   "나열만 하면 별로" → 위로 한 칸씩 올라가며 위에서 사라지고 아래에서
   다시 이어지는 띠. 상담하면 어떤 반이 모집 중인지 계속 보이게 한다.

   구현 원칙
   · 목록을 두 벌 복제해 트랙을 만들고 -50%만큼 이동 → 끝과 시작이 같아
     이음새 없이 무한 반복된다.
   · 각 항목이 margin-bottom(gap)을 직접 가지므로 한 벌의 높이가 정확히
     트랙 높이의 절반이 된다(간격 누적 오차 없음).
   · 위·아래 끝은 mask로 흐리게 — 딱 잘린 느낌을 없앤다.
   · hover/focus 시 정지, prefers-reduced-motion에서는 애니메이션 없이
     스크롤 가능한 정적 목록으로 대체한다.
