   AKU Portfolyo — ziyaretçi sitesi
   ------------------------------------------------------------
   Tek görsel kimlik: maviden mora geçen vurgular, beyaz ve nötr
   tonlarla dengelenmiş açık ve koyu görünüm.

   Görünüm <html data-gorunum="koyu|acik"> ile seçilir:
     - sunucu varsayılanı basar (panelde seçilen ilk görünüm),
     - ziyaretçinin ay/güneş tercihi theme-init.js ile uygulanır.

   Geçişli renk (gradient) yalnızca vurgu için kullanılır:
   başlıktaki vurgu, birincil düğme, seçili öğe, süreç çizgisi.

   Yönetim paneli bu dosyayı KULLANMAZ (admin-base.css).
