/* EAI City — design system v6 «Premium». The city fills the screen; calm glass UI floats over it; everything else opens as

   Warm paper, white panels, hairlines; one confident primary (deep petrol), a warm gold accent for rewards and «Для вас».
   Legacy token names (--blue, --yellow, --green …) stay and point at the new palette, so every module restyles at once. */
