   HERO SECONDARY — hero-secondary.css (v10)
   daphone-landing-page

   2026-04-20 v10 변경 (v9 → v10):
     ★ min-height: 100vh 추가
        → HERO 섹션과 동일한 높이 체계 구성
        → 섹션 하나만으로도 안정적인 세로 중앙정렬 보장
        → 중복 섹션으로 땜빵하던 방식 제거
     ★ padding-block 유지 (콘텐츠와 경계 사이 여유)
     ★ grid + place-items: center 유지 (중앙정렬)

   v9 유지:
     - Ken Burns 제거 (모바일 블러 방지)
     - will-change 제거
