   Портфолио — редакционная дизайн-система.

   Тёплая бумага, волосяные линии, Playfair + Inter + JetBrains Mono.
   Никаких пилюль, неона, градиентов, иконок и декоративных теней:
   структуру держат линии, сетка и типографика.

   Правило чтения: текст контрастный, линии заметные, секции разделены
   волосяной линией по ширине колонки и воздухом, поверхности — плоские.
