/* ============================================================
   PREMIUM ROLLING SHUTTER PRELOADER
   Demirdelen.com — Kurumsal açılış animasyonu

   Konsept korundu: metal kepenk alttan yukarı akıcı şekilde kalkar.
   Yenilendi: tek parça düzgün metal lameller (repeating-linear-gradient),
   metalik ışık süzülmesi, gerçek progress bar, daha yumuşak easing.
   Sadece oturum başına bir kez oynar (sessionStorage).
