/* The demo's own styling, loaded after the site theme's stylesheet.

   Every rule is scoped to the page's `.demo` wrapper, so nothing here reaches
   the site's header, footer or search dialog. The colours are the theme's own
   tokens, which is what makes the demo follow the header's theme toggle; the
   few the theme has no token for -- a soft accent fill, warning and error --
   are defined here for both palettes, in the same dark-first way the theme
   defines its own. Deliberately plain otherwise: the interesting stylesheets
   are the ones compiled in the preview frame. */
