/* CoachAI, the house style. Monochrome and bold, after the logos: black on
   white, heavy type, one action per screen. Built to be read on a phone at the
   range in sunlight, so contrast is maximal, every control is a large target
   that works with a gloved thumb, and nothing depends on hover. */
