/* LaserGrav PRO — айдентика «рисунок на металле».
   Холодный матовый алюминий как фон, чернёная сталь как текст и тёмные блоки, одно рубиновое пятно — цвет лазерной точки.
   Главный приём один: заголовок «выгравирован» бегущей лазерной линией при загрузке. Остальное спокойно: линейки вместо карточек, плоские кнопки. */
