   POWERRA — дизайн-система

   Чёрный — основа, золото — главный акцент (кнопки, цифры, выделения),
   красный — только узкий: полоса-триколор, скидка, «не подойдёт».
   На кнопках красного нет: на чёрном он читается как ошибка.

   Цвета схемы электроснабжения несут смысл и остаются отдельными:
   золото = солнце и DC, синий = сеть и AC, зелёный = накопитель и
   «в наличии».

   Шрифт заголовков и цифр — Onest (свой, с кириллицей), основной
   текст — системный. Моноширинного нет: цены и характеристики набраны
   табличными цифрами того же Onest.
