/* HTServis — site.css (v3)
   Kimlik: "teknik çizim" — grafit ve kâğıt beyazı zemin, tek vurgu rengi (sinyal mavisi),
   ince kılavuz çizgileri, mono ölçü etiketleri, iki tonlu başlıklar.
   Neden grafit? Lacivert her yerde olunca sıradan SaaS gibi duruyor; nötr grafit logonun
   siyah-kırmızısıyla çatışmıyor, mavi yalnızca etkileşimi işaret ediyor. */
