/* Stack Tower — a calm isometric tower under a sky that changes with height.
   The canvas fills the window; the interface floats over it as frosted glass.
   [data-theme] sets dialog colours, [data-sky] (light/dark, from the sky's
   brightness at the current height) sets the ink of everything over the sky. */
