   Tek bir stil katmanı. Bölümler: token'lar → temel → yerleşim → bileşenler →
   bölüm stilleri → hareket → duyarlılık.

   Renk kararı: markanın vurgusu yeşil (bull), ama arayüzün birincil vurgusu MAVİ
   (depth). Yeşil piyasaya ait bir anlam taşıyor — yükseliş, dolan emir — ve onu
   düğmelere harcamak o anlamı köreltiyor. Mavi arayüzü, yeşil piyasayı anlatıyor.
