   ⚠️ Bu dosya HİÇBİR sabit marka rengi içermez. Tüm renkler --brand-* CSS
   değişkenlerinden gelir; değişkenler kongre ayarlarından <head>'e basılır
   (bkz. themes/base/layout.blade.php).

   Sonuç: kongre başına CSS derlemesi YOK. Aynı tema, farklı palet = farklı
   kongre görünümü. Ayrı tema açmak yalnız gerçekten farklı bir YERLEŞİM
   gerektiğinde gerekir.
