/* SEE IT — watch Complly work (mock-up, 18 Oct 2026; Epic #299 / #301). Risk and Construct each get a captioned
   walkthrough of real product screens on a made-up company; FRA and Inspection are honest "in development" rows;
   Try it live hands over to the existing demo. Owner, 18 Oct: "keep this at Risk and Construct for now".

   🔑 THE PAGE MUST LOOK FINISHED WITH STILLS ALONE (the epic's own rule). So the "player" is a slideshow of stills
   with subtitles, not a video that may never arrive. When recordings exist, the same frame takes a <video> and the
   step list becomes chapters; nothing else on the page changes.
   🔑 It uses the site's own tokens (--p-risk, --p-construct …) and the thread's chip style, so a product is the same
   colour here as on Our apps. */
