/* =========================================================
   Технический аудит САПР и ИТ-ландшафта — Нормасофт
   Приоритет: 1) шрифт Manrope  2) токены DESIGN.md  3) стиль презентации

   Правило интерфейса — два визуальных языка, без исключений:
   • Интерактивное (кнопки, вкладки, summary, документы, стрелки, ссылки-карточки):
     рамка или заливка + срез угла, обязательный признак действия (+/−, →, ←, «i» — подсказка,
     подчёркнутая ссылка), hover и :focus-visible, cursor:pointer, высота ≥ 40–44 px.
   • Неинтерактивное (теги, факты, цифры, метки, бейджи): плоско — без рамки, тени,
     стрелок и hover; мелкий текст 500.
