/* -------------------------------------------------------- üç mod
   "Harmoni" varsayılan moddur: zemin marka lacivertinin ta kendisi
   (#162D63) — gece'nin saf siyahından bir tık açık, gündüz'ün beyazından
   çok uzak; logomuza en yakın duran seçenek. Gece tamamen siyaha yakın,
   gündüz ise markanın en açık, beyaza yakın tonu — ve bu ikisinde metin
   rengi de yer değiştirir (gündüzde koyu metin, diğer ikisinde açık metin).
   Neredeyse tüm bileşenler --ink/--t-on-dark token'larını kullandığı için
   tek blok değişince site geneli tutarlı tepki verir. Sabit koyu kalan
   tek yer video/fotoğraf üstü scrim'ler (nav, hero, sahne kartları) —
   bunlar bilinçli olarak temadan bağımsız, çünkü görsel üstü metin her
   zeman aynı türde (koyu perde + açık yazı) okunabilirlik ister. */
