/* Glide Maze — one stylesheet.
   Visual concept: three hand-drawn worlds (Ice, Cave, Desert), each by day and by
   night; soft light from the top left, rounded shapes, a fine grain; calm,
   translucent 14 px panels over a slowly living landscape. Motion explains:
   things glide, settle with a small spring, pop, fade — transform and opacity
   only, and plain fades with reduced motion. */
