/* Switching Cost's thin shell on the kit's Live Stage tokens (vendor/exercise-kit/web/live-stage.css, linked first as
   /kit/live-stage.css). Pages rely only on the aliases and the .sc-* classes below, so moving the screens onto the kit's
   phone and wall shells later changes no page code. Fallbacks keep the look if the kit stylesheet is missing. */
