/* Number wheel (client/number-wheel.jsx): a swipeable strip of numbers that
   snaps under a highlighted lens, with - and + either side. Styled to sit in
   the dark setup panels: a recessed pill track like the game-length segments,
   and the same gradient-with-yellow-edge highlight as a selected segment, so
   "the chosen one" looks identical everywhere in setup. */
