   ProFaber — sayt uslubi

   Dizayn tili profaber.io dan olingan (Next.js + Tailwind), bu yerda toza
   CSS ga ko'chirilgan. Uchta brend motivi butun sahifada takrorlanadi:

     1. Chamfer — o'ng pastki burchak 45° kesilgan. Belgidagi kesim shundan.
     2. Ruler   — bo'limlar orasidagi ajratgich chizg'ich qirrasi ko'rinishida.
     3. Hex     — modul belgilari olti burchak (bolt boshi) ichida turadi.

   Rang qat'iy: qog'oz (--paper) va oq navbatlashadi, urg'u faqat to'q sariq
   (--accent), qorong'i bo'limlar (--ink) taqqoslash va CTA uchun.
