/* «Просто» — стиль petkevich.kz с 28.09.2026.
   Принцип Ильи: всё гениальное просто — инновационность, удобство, простота,
   стиль. Отсюда: белый лист, чёрный текст, много воздуха, тонкие линии и один
   сигнальный оранжевый (как у Braun — «меньше, но лучше»). Заголовки —
   антиква Source Serif 4, текст — Manrope; шрифты свои, /site/templates/fonts/.
   Фон — тонкая сетка, которая проявляется только вокруг курсора (чистый CSS,
   позицию задаёт pk-simple.js). Слой идёт ПОСЛЕ импортированных Astro-стилей и
   меняет в первую очередь их переменные; разметку и SEO не трогает. */
