   --- ЗАЩИТНЫЙ ФИКС: контраст текста на primary/danger фонах ---
   Любой элемент, у которого в :hover/:active/.active/.is-selected
   появляется синий/primary/danger фон, должен показывать белый текст
   и белые иконки. Глобальный `button { color: #fff }` покрывает только
   сам <button>, но не вложенные <span>/<svg> и не не-кнопочные элементы
   (ссылки, .menu-item, .service-row, .cat-item, и т.п.).
   Эти правила — последняя линия обороны. Не отключай их и не считай
   основным способом: правильнее явно прописывать color в :hover/active
   рядом с background (см. AGENTS.md, раздел "Контраст текста на цветных
   фонах"). */
