/* ==========================================
   ANA SAYFA HERO — marka görseli
   Beyaz zemin. Ortada panelden yüklenen marka görseli "pat" diye belirir,
   hafifçe süzülür ve imlece doğru eğilir; arkasında sarı ışık halkası ve
   zıt yönlere akan soluk dev hizmet adları, çevresinde parıldayan yıldızlar.
   Altta ortalı başlık (son kelime sarı fosforlu kalem), kısa metin, butonlar.
