/* ==========================================================================
   Alarko Carrier AI Paneli — koyu tema
   --------------------------------------------------------------------------
   Bootstrap 5.3'ün kendi koyu modu (data-bs-theme="dark") temel alınır; burada
   yalnızca Bootstrap'in CSS değişkenleri kendi paletimize çekilir. Böylece
   kart, tablo, form, dropdown gibi bileşenler tek tek ezilmek zorunda kalmaz.

   --ac-navy sayfalarda satır içi style ile kullanılıyor (buton ve ilerleme
   çubuğu arka planları). Değişkeni silmek yerine yeni vurgu rengine
   yönlendiriyoruz; böylece sekiz sayfa düzenlenmeden tutarlı kalıyor.
