   Saf statik HTML/CSS/JS — framework yok, build tool yok.
   Mobile-first. Üç katmanlı token yapısı: primitive → semantic → component.

   KURAL: TÜM hex (#) renk değerleri yalnızca aşağıdaki :root token
   bloğundadır. Bileşenlerde yalnızca var(--token) kullanılır.

     3.  Utilities
     4.  Layout (header/nav/footer)
