/* ---------------------------------------------------------------------
   UPS Monitor — дизайн-система
   Тёмная палитра в духе референсов + акцентные цвета, унаследованные
   от десктопной версии (голубой/оранжевый/розовый/зелёный на метрику) —
   чтобы веб- и десктоп-версия читались как один продукт.
   Типографика: Space Grotesk (заголовки/крупные цифры) + Inter (текст) —
   геометричный, "электрический" характер вместо дефолтного Roboto.
   Material Design здесь — про elevation/motion/state-layers, не про
   конкретный шрифт Google.
