   Fluid sizes interpolate between the mobile frame (390px) and the
   desktop content width (1300px). All sizes are in rem: on desktop the root
   font size follows the screen width, so the whole layout scales like the
   1920px Figma frame (100% at 1920px, 80% at 1536px, 75% at 1440px and below).
