/* Ninja Arena 3D — "arcade dojo" design system.

   One colour per meaning, so a 9-year-old can read state at a glance:
     cyan = you / primary action / selection   magenta = opponent, High level
     amber = points, score, costs, Mid         green = correct, win, Junior
     red = wrong, damage, overheat
   Stat colours are fixed app-wide: Speed cyan, Power orange, Strength green,
   Frame violet.

   Layout is decided by INPUT as well as width: touch controls and big hit
   targets follow `html.input-touch` (set from (pointer: coarse) in main.js), key
   hints follow `html.input-kbd` (set the moment a real keydown arrives). */
