   KURUÇAY ENDÜSTRİ — tasarım sistemi
   Renk ve motifler markadan türetildi:
   · zemin      → logo ozalitinin mürekkebi
   · mavi çizgi → teknik resim kılavuz çizgisi (yapı, vurgu değil)
   · turuncu    → CNC soğutma hortumu rakorları (tek sıcak vurgu, ~%5)
   · ölçü çizgisi + eğik terminatör → wordmark'ın üstündeki imza motif
   · altıgen    → ikincil marka işareti
