   XNEXUS — css/demo-studio.css
   Call System Simulation Studio (2026-08-29)
   ============================================================
   Sits above the existing Demo Request form (#demo-request-section).
   Purely visual/interactive — no field here is submitted with the
   Demo Request; the actual form below is completely untouched.
   Uses the site's existing custom properties (--bg/--purple/--blue/
   --cyan/--text-dim/--grad-text, all defined in core.css) rather than
   inventing a parallel palette, so this reads as part of the same
   site, not a bolted-on widget.
