   Детейлинг-студия «АПЕКС» — демо-проект CloudxBear
   Дизайн-ДНК: глянцевый премиум. Чёрный глянец #0c0d10 +
   ледяной циан #46d5e6 + хром-серебро. Play (дисплей) +
   JetBrains Mono (цены/спеки) + Inter (текст). Единственное
   оправданно-тёмное демо — люкс-авто.
   Фирменные приёмы: блик по глянцу за курсором, морф цен по
   классу авто, до/после со скользящим бликом, капли воды.
