   Выбор поколения автомобиля: поле «Поколение» + выпадающая панель под строкой
   фильтров. Стилистика повторяет панели марки/модели; тело — плоская сетка
   «код кузова + годы» с фильтром по префиксу (Все / E / F / G).
   Пути к иконкам указаны относительно /frontend/web/css/
   ВАЖНО: на сайте есть глобальный стиль button { width:100%; ... }, поэтому все
