   Eskiden bu kurallar .m-screen.light-mode / .m-screen.dark-mode sınıflarına
   bağlıydı ve sınıfı JS, DOMContentLoaded'da atıyordu. HTML'de ise sınıf sabit
   "light-mode" yazıyordu; sitenin varsayılanı koyu olduğu için telefon her
   açılışta önce BEYAZ boyanıp sonra koyuya dönüyordu. Diller arasında geçerken
   göze çarpan sıçrama buydu.
   Artık kurallar <head> içinde, boyama başlamadan önce ayarlanan
   data-theme özniteliğine bağlı; sınıf beklemeye gerek kalmadığı için
   telefon ilk karede doğru renkte çiziliyor.
   :not([data-theme="light"]) yazılmasının sebebi: JS tamamen kapalıysa
   öznitelik hiç oluşmaz, o durumda da sitenin varsayılanı olan koyu geçerli. */
