/* =================================================================
   Smart Paste demo — animated product demo in the homepage demo
   style (chat-demo.css): white window, soft bar, real-looking UI.
   States are driven by data-step on .sp-demo (see js/smart-paste-demo.js):
     idle → keys → menu → fill → done
   The markup ships in the final "done" state, so no-JS and
   prefers-reduced-motion visitors see the finished frame.
