   Doni Proxy — Motion / Transitions Layer (v1.0)
   ============================================================
   Подключается ПОСЛЕ design-system.css и tailwind.min.css.
   Дополняет фирменные плавности, hover-state и анимации
   появления для модалок, чата, кнопок и карточек.
   prefers-reduced-motion → полностью отключает анимации.
