/* The Machine Studio's look (docs/studio.md; js/studio/view.js): one
   stylesheet for every spec machine, dressed in its art kit. Every colour
   is a kit token (--kit-*: the palette, for rims and glows only) or a
   studio tone (--studio-hall, -glass, -glass-light, -plate: contrast-safe
   surfaces, the only ones text sits on), set by the view on #app, the
   sign, the reveal and the help pages (.pt-studio), with the shared
   tokens as fallbacks. Scoped to .app.studio, .studio-sign, .studio-show

   scene (css/scene-motion.css) and still under reduced motion. */
