   Mühlermak — stil ve animasyon katmanı

   MARKA KURALI
   Logo yalnizca #ff6b35 renginde ve yalnizca Freehand 521 yazi
   stiliyle gorunur. --brand bu renktir ve degistirilmemelidir.
   Beyaz uzerine turuncu METIN gerektiginde --brand-ink kullanilir
   (#ff6b35 beyazda 3.0:1 kontrast verir, normal metinde AA'yi
   gecmez). Logo hicbir kosulda --brand-ink kullanmaz.

   ANIMASYON KURALI
   Yalnizca transform ve opacity animate edilir. Scroll'a bagli
   bolumler --p (0→1) degiskenini okur; bu degeri main.js'teki tek
   rAF dongusu yazar.
