/* 25 · Slayt modu + bölüm rayı --------------------------------------------
   Ana sayfa (front-page.php, .yb-slides) geniş ekranda slayt gibi akar: her bölüm bir

   yapar; main.js yalnızca <html> öğesine .yb-snap ekler, tekerleği ele geçirmez.
   Yalnızca ≥768px + ince imleç + hareket azaltma kapalıyken. Telefon, dokunmatik ekran ve
   hareket azaltmada sayfa eskisi gibi serbestçe kayar (bu kurallar hiç devreye girmez).
   Ekrandan uzun bir slayt kesilmez: zorunlu yakalama, ekranı kaplayan uzun bir slaydın
   içinde serbest kaydırmaya izin verir; sonra bir sonraki slayda geçer.
   scroll-snap-stop: always hızlı bir savurmanın (dokunmatik yüzey, serbest dönen tekerlek)
   slayt atlamasını önler; raydan / menüden yapılan atlamaları etkilemez.
   Hassas (piksel) tekerlek girdisinde küçük bir hareket, syndra.yakupbilgin.com'daki gibi
   aynı slayda geri yakalanır; tekerlek bilerek JS ile ele geçirilmez.
