/* ---------------------------------------------------------------------------
   The landing page's demo (Components::MarketingShowcase): four scenes played
   on a phone drawn in CSS — no images, no video.

   How it plays: showcase_controller.js gives the scene that's on [data-active]
   (shown) and [data-play] (animating). Every timeline below hangs off
   [data-play], and every element's resting style is its LAST frame, with each
   animation filling `both` from its first. So a scene that isn't playing
   shows how it ends, the same frame reduced motion and no-JavaScript visitors
   get, and starting one is just adding the attribute. What moves is
   transform and opacity, which the browser composites without laying out
   the page again — all but the typed search word, which widens a letter at a
   time.

   The tab meters are the clock: the active one fills over --sc-duration and
   its animationend moves the controller to the next scene. [data-paused] stops
   every animation at once, the clock with them.

   The screen is laid out in px on purpose: the scenes move things to fixed
   spots (a receipt shrinking into the chat, a search result sliding up), so
   the screen can't reflow under them. Small phones get the whole thing
   zoomed instead.
