 * birebir karşılığı. Oradaki değerler değişirse burası da değişmeli —
 * iki sürümün aynı görünmesi buna bağlı.

 * Poppins Google Fonts'tan DEĞİL, kendi sunucumuzdan yükleniyor
 * (assets/fonts/). Sebep: masaüstü sürümde font gömülü geliyor, aynı
 * görünmesi için aynı dosya lazım; ayrıca dış bağımlılık = ders ortasında
 * Google'a erişilemezse yazı tipi bozulması demek.
