/* Little Lantern - the Tending Game.
   Calm, pastel, low-saturation base with a few saturated accents on the two
   touchable tools (P18). Big targets (P02). Small, slow, interruptible motion
   that switches off under reduced motion or in the evening (P19, P20). A warm
   overlay veils the scene as evening comes on (P14). */
