   Design tokens

   Taken from the approved design. The mockup expressed its tracking in fixed
   pixels (`letter-spacing:-3.5px` on a heading that clamps from 70px down to
   40px); those are converted to `em` here at the ratio the design used at its
   reference size, so the same tightness holds instead of turning into a crush
   at the small end of the clamp.
