 *  Bütün sınıflar "tka-" önekli; çekirdeğin site.css'ine dokunmaz.
 *  Renkler cilginyazilim.css token'larından gelir: tema rengi
 *  (Ayarlar → Sistem) ve koyu tema kendiliğinden uygulanır. Karşılama
 *  ve son çağrı bandı her iki temada da koyu zeminlidir.
 *
 *  HAREKET: anasayfa.js <html>'e "tka-hazir" ekler; görünür olunca
 *  belirme yalnız o sınıf varken çalışır (JavaScript kapalıyken her
 *  şey baştan görünür). "Hareketi azalt" tercihinde bütün animasyon
 *  ve geçişler kapanır (dosyanın sonu).
