   Ground is a blue-toned night rather than neutral black, so the three session
   colours read as a temperature ramp against it: chalk cyan for aerobic work,
   sodium amber for tempo, flare magenta for intervals. Type is Archivo for
   voice and IBM Plex Mono for anything measured — every number on this page is
   an instrument reading, and none of them should reflow as digits change.
