/* THE DUEL — one screen, one cabinet.
   Fit rules: the page itself never scrolls (html/body are exactly one viewport tall,
   overflow hidden); everything that does not fit in the arena or the command menu
   lives in a floating window, opened from a button. The two fighters are sized by the
   height of the row that is left over, so shrinking the HUD makes them bigger. */
