   Mimari:
     1. Tasarım belirteçleri (tokens)
     2. Sıfırlama (reset)
     3. Temel öğeler (base)
     4. Düzen (layout)
     5. Bileşenler (components)
     6. Sayfa bölümleri (sections)
     7. Duyarlılık (responsive) — mobil öncelikli değil, kademeli iyileştirme
     8. Hareket azaltma ve yazdırma

   NOT: Tüm masaüstü stilleri burada tanımlıdır. Daha önceki sürümde iç
   sayfaların stilleri yanlışlıkla @media (max-width:680px) bloğunun içine
   gömülüydü; bu nedenle masaüstünde tamamen stylesiz kalıyorlardı.
