   Meteo Wave — meteowave.com
   Static, no build step, no framework.

   The page is a film. One WebGL stage and one particle canvas
   sit fixed behind fifteen sticky chapters; the living phone and
   the sun-dial are fixed above them. Chapters carry the copy;
   the stage carries the weather. See js/timeline.js.
