   the step on the left, the pack and what is limiting it in the middle, the
   live summary on the right, the charts beneath. Everything is built from
   the site's own tokens, so the light and dark themes and the skins restyle
   it; the chart colours below are the only values of its own, chosen to
   read at 3:1 or better on both a dark and a light ground.
