   Arena - the employee surface. Phone only, dark, read at arm's length in a
   noisy room. Every value here resolves from tokens.css, so applying the NICE
   palette later is a one-file change.

   Deliberate departures from the previous build: content is left-aligned rather
   than centred down the middle, there is one accent moment per screen instead
   of a gradient on every element, and numbers sit on their own optical baseline
   because they are the point of the whole exercise.
