   size-adjust matches the average glyph width of the web font over an

   moves text as little as possible.
   Weight 800 is tuned to the hero (opsz 96); the weight 700 faces stand in for
   buttons and labels, which render as 800 at opsz 18, and are tuned to that. Values come from fontTools measurements; see
