/* ---- Marka filigranı ------------------------------------------------------
   Sayfanın tamamını kaplayan, soluk Opet logosu (web/opet-logo.webp).
   Sabit konumludur: sohbet kaydıkça kaymaz, arkada durur.

   Renkler korunur, yalnızca soluklaşır — grileştirme yok. Logonun şeffaf zemini
   olmadığı için sarı bir kare içinde gelir; ekranın TAMAMINI kaplattığımızda o
   kare kenarı diye bir şey kalmaz, sarı sayfaya yayılmış bir marka zeminine
   dönüşür. `cover` bu yüzden hem istenen görünüm hem de kare sorununun çözümü.

   Zemin #F3F5F9 üzerinde %16 opaklıkta:
     sarı  #FFD300 → #F5F0D1   (yumuşak krem)
     mavi  #134FAE → #CFDAED   (yumuşak mavi, kelime markası okunur)

   Tek ayar düğmesi opacity'dir: .20 daha doygun, .10 daha soluk.

   İçeriğin arkasında kalması için .app şeffaflaştırılır; başlık ve besteci
   kendi opak zeminlerini taşımaya devam eder, böylece metin her zaman okunur
   bir yüzeyin üstünde kalır. */
