/* style.css: THE SCENE (layout, title card, player). The skeletons are in parade.css.

   THE STAGE is one 16:9 box that covers the screen like a video would. The video AND the
   parade live inside it, so anything placed in % lands on the same spot in the video frame,
   on every screen size. On tall screens (phones) it zooms out to show the path, over a
   blurred copy of the cemetery. */
