/* ---------------------------------------------------------------------------
   Embedded app demo.

   This is a port of the real client's stylesheets - apps/desktop/src/renderer/
   src/assets/styles/{layout,components}.css plus the per-view scoped blocks -
   scoped under .appdemo so the marketing page's own rules can't reach in and
   the app's rules can't leak out.

   The token block below is the app's palette, NOT the site's: the site's --seal
   is brand navy, but inside the app green/amber/red have to keep meaning
   clear/review/flag or the status badges stop being readable.
