/* walkthrough.css — shared interactive step-player used across the docs and
   the landing page. Self-hosted "Supademo-style" walkthrough: a real captured
   screenshot per step, a highlighted hotspot pointing at the exact control,
   and a caption — with both auto-advance (feels alive, like a video) and full
   manual control (click/keyboard, feels interactive, unlike a video). */
