/* ==========================================================================
   OpenVids landing — outro mini demo ([data-dm], built by openvids-landing-demo.js).
   A scoped miniature of the Edit workspace (openvids-editor.html). Rules are ported 1:1 from openvids.css,
   openvids-editor*.css and openvids-chat.css with dm- prefixes; the app's dark tokens are declared on the
   demo root so nothing leaks into (or in from) the landing. Accent: selection + focus rings only.
   .dm-x = chrome the demo does not implement: rendered, inert (no pointer, no focus, no hover).
