   Renkler tek yerde, iki tema. Açık tema varsayılan; koyu tema hem sistem
   tercihinden hem de [data-tema="koyu"] ile açılır, böylece kullanıcının
   seçimi sistemin üstüne yazar.

   Kod blokları iki temada da koyu: vurgulama renkleri sabit kalıyor ve
   metinle kod arasındaki sınır her koşulda görünür oluyor.                */
