/* Hide the separate cart icon on desktop, we use the one in nav-links usually?

   The user said "leave the cart out of the hamburger menu".
   If I removed it from nav-links, I should show it in .nav-right on desktop too!
   So .desktop-cart-hidden should actually be visible on desktop?
   "cart on the left of the menu"
   If I show it in .nav-right, it will be to the left of hamburger (if visible) or just on the right side.
   Let's assume we want it visible always now.
   So I won't use .desktop-cart-hidden to hide it on desktop.
   I will just style .nav-right.
