      .delay-1 { animation-delay: 0.1s; } ...

  Bu blok dosyanın başındaki (satır ~81) scroll-reveal sistemini eziyordu.
  Sonuç: tüm öğeler sayfa açılır açılmaz aynı anda animasyon oynatıyor,
  aşağı inildiğinde hiçbir şey animasyonlu gelmiyordu. Kaldırıldı —
  scroll reveal artık yukarıdaki .fade-up / .fade-up.visible ikilisiyle
  ve js/effects.js içindeki IntersectionObserver ile çalışıyor.
