  Визуальный язык "ЗАСТУП": острые прямые углы (никаких скруглений), плотный
  жирный Archivo, тёплый кремовый фон и чёрный текст с ярко-красным акцентом,
  толстые 2px разделители вместо привычных теней. Токены и часть компонентных
  классов (.btn, .card, .tag, .input, .dialog, .hr) взяты из дизайн-системы
  "Modernist", присланной пользователем как эталон.
