/*
  İşteÇözüm kurumsal site — tasarım sistemi
  Renk: logonun kendi moru (#675DA4) tek eylem rengi; başlık ve koyu alanlar lacivert mürekkep (#1E1C38); zemin beyaz kâğıt.
  Yazı: Hanken Grotesk (tek aile, değişken ağırlık, kendi sunucumuzdan) — sayılar tabular.
  Yapı: kart yerine ince çizgi ve boşluk; kenarlık yalnız form ve seçim kutularında; süs dokusu yok.
