   Bölüm istifi
   Her bölüm bir öncekinin üstüne yuvarlak köşeyle biner ve yapışarak
   (sticky) altındaki bölümün üzerinden kaymasına izin verir.

   Yapışkanlık .is-stacked sınıfına bağlı ve `top` değerini main.js veriyor:
   - viewport'a sığan bölüm  → top:0   (üst kenardan yapışır)
   - viewport'tan uzun bölüm → top:vh-h (negatif; ALT kenarından yapışır)
   İkinci durum şart: top:0 ile uzun bir bölüm tepeye çivilenip alt içeriği
   bir sonraki bölümün altında kalıyor ve hiç okunamıyordu. Negatif top ile
   bölüm, alt kenarı viewport'un altına gelene kadar normal kayar; ancak
   tamamı okunduktan sonra yapışır. JS yoksa efekt devre dışı kalır, sayfa
   yalnızca binmeyle sorunsuz çalışır.
