/* ClearRun Demo Widget — scoped styles.
   All rules prefixed with .cr-demo-widget to avoid bleeding into host page styles.
   Relies on CSS variables defined on :root in styles.css. If loaded standalone,
   the test page provides a minimal :root fallback.

   Two themes:
     .cr-demo-widget           — default light theme (works on white/off-white hosts)
     .cr-demo-widget--glass    — frosted-glass theme for dark/gradient hosts
