/* ===========================================================================
   Atlas Kurumsal — theme.css
   Sanat yönü: "Cesur Editoryal"
   Koyu mürekkep zemini, kireç yeşili + menekşe ikili vurgu, dev tipografi,
   keskin köşeler (4–8 px), kalın ayraç çizgileri, numaralı bölümler.

   Kurallar:
   • Ham hex YALNIZCA :root altındaki değişken tanımlarında bulunur.
   • Yapısal katman assets/base.css'ten gelir; burada yalnızca sanat yönü var.
   • Tüm animasyonlar transform/opacity üzerinden çalışır (60 fps hedefi).
