/* ============================================================
   Animations — protótipo Rosceli 2026
   Camadas:
   1. Fade-up ao rolar (IntersectionObserver disparada em animations.js)
   2. Stagger interno (cada filho aparece com delay incremental)
   3. Hover lift em cards (Plans / Services / FAQ rows)
   4. Parallax leve em fotos (animations.js)

   Todas as animações respeitam prefers-reduced-motion.
