   A cool, quiet showroom where the work is the hero. Huge, tightly tracked
   headlines whose second half drops to grey; each piece of work on its own
   large rounded plate with its own ground, display face and button, shown
   in an overlapping browser + phone frame that can be played live.
   Requires tokens.css. The drawn work inside the frames lives in the page
   (or css/work.css); this file only gives it a vocabulary (.w-* classes).
   Motion is on by default unless the visitor prefers reduced motion;
   html.calm (the footer Motion switch) stills it.
