/* ============================================================
   Арсений Кудрявцев — портфолио
   Мир: ретро-брутализм / webflow-mockup сетка. Чёрное на белом,
   толстые (4px) чёткие векторные обводки на каждом элементе —
   без скетч-эффекта, halftone-точки — единственный источник
   фактуры (звёздочка у имени + адресная строка/экран плеера),
   жёсткие тени без blur на "коробочных" элементах. Golos Text
   (800) = тяжёлый гротеск для имени/заголовков, JetBrains Mono =
   вся остальная типографика (навигация, лейблы, тело, чром окна).

   Обводки теперь plain CSS border (не SVG): jitter-фильтр убрали
   ещё на прошлом проходе, а стретч-фит SVG-техника имела смысл
   только ради него — обычный border даёт тот же чёткий результат
   проще. SVG остался только там, где нужна форма/паттерн, которые
   CSS border не может: уголки-метки, halftone-звезда, шеврон,
   play-треугольник.
