/* ===========================================================================
   Nexus console design system — used ONLY by the /demo/* pages.
   ---------------------------------------------------------------------------
   These are simulated Nexus workspace screens linked from the home page chat
   demo. The tokens and component classes below are lifted from the platform's
   own `nexus-console-style-guide` skill so the mock looks like the real
   product; keep them in step with it rather than restyling them to match the
   marketing site (assets/site.css). The two systems are deliberately separate —
   do not link both into one page, and do not add `nx-` classes to site pages.
   No JavaScript: every screen here is a still frame.
