/* Stella's games: one calm look for every game.
   Soft pastels on cream, a warm brown ink instead of black, big round
   shapes, slow and small movement. Made for a 3½-year-old on an iPad:
   everything she can touch is at least 96 px, nothing flashes, nothing
   moves on its own for long, and nothing needs reading. */
