/* Veydr Labs demo kit — shared by every demo in public/demos/.
   It gives each demo the site's colours and type as --vl-* variables, and draws the bar at the
   top left: the "Back to Veydr Labs" button and the name of the format being shown.
   Each demo's own restyle is in the file beside this one that carries the demo's name. */
