/* Clovermind, the homepage's pencil Pong.
   Only what the game needs inside the hero figure: the board's box, the
   canvas, the play and pause controls and the failure note. The card around
   it, the layout and the caption belong to main.css.

   The board reserves its 2:1 box before the script runs (no layout shift)
   and shows the pencil paper colour, so there is no flash before the paint.
   Override --hero-pong-radius to match the card the board sits in. */
