   ATLAS Mimarlık — İskandinav çizgi. Tek fikir: GÜN IŞIĞI.
   Bakır güneş noktası (--sun) ufuk çizgisinde yürür; sayfa aşağı indikçe gün ilerler, footer akşamdır.
   Yazı: Familjen Grotesk (başlık) + Alpino (metin) — tamamen sans, yerel woff2.
   Renk: neredeyse beyaz kâğıt, antrasit mürekkep, çam yeşili alan, bakır güneş. Köşeler keskin.
