/* VentLink — панель. Графитовая рейка с логотипом, светлое рабочее поле, графитовый приборный блок.
   Фирменные цвета: графит #111111, индикатор #E8692A, белый. Шрифт Inter Tight. Формы — почти прямые углы,
   индикаторы состояния — квадратные, как индикатор в знаке.
   Цвет воздуха: свежий (наружный и приток) — синий, удаляемый (вытяжка и выброс) — оранжевый. */
