/*
  BackupShift marka sistemi — Tray uygulamasındaki AccentBrush (#E8A33D) ile aynı altın vurgu
  rengi kasıtlı olarak burada da kullanılıyor: ürünün masaüstü ve web tarafı aynı markaya ait
  hissettirmeli. Lacivert (#14213d) ana sayfadaki hero bölümüyle aynı — giriş ekranından panele
  kadar tutarlı bir görsel kimlik.
