/* Uygulama portalı — apps.bitwork.com.tr
 *
 * Ana sitenin tasarım sistemini kullanır: token'lar, yazı tipleri ve
 * tipografik ölçek `tokens/tokens.css` ile birebir aynı değerlerdir
 * (ana sitenin derlenmiş çıktısından alındı). Burada yeni token
 * türetilmez — renk ya da ölçü gerekiyorsa mevcut token kullanılır.
 *
 * Site koyu katmanda çalışır; ana site de temayı belge köküne `dark`
 * olarak damgalıyor. Burada aynısı yapılır, açık tema dalı yoktur.
 *
 * Buton ve kart bileşenleri ana sitede @bitwork/ui'den geliyor; bu
 * kurulumda o kütüphane yok, o yüzden aynı token'larla yeniden yazıldılar.
