/* Shared layout for every game demo (loaded after style.css, uses its tokens).
   Fixed places, the same in every demo:
     top bar ......... Kashio Games / <game> / デモ (links back)
     left column ..... status row (turn | info), message, the board (square), board actions (game-specific, under the board)
     right column .... common controls first (undo, restart), then game-specific controls, settings, how to play, rules
   On narrow screens the right column moves under the board. */
