/* Plays -- study build.
   Deliberately plain. The arena page uses a high-contrast red-on-black look
   that reads as "something is wrong here"; a study page should read as a
   board game and nothing more. One accent, used for focus and for the
   player's own marks, never to distinguish one legal move from another. */
