/* ---------------------------------------------------------------------------
   The Help Center (Pages/Help): the help home, the search, and the guide reader.

   Sober on purpose - it is documentation inside a back-office tool. Flat white
   surfaces, thin lines, the accent only for links, selection and the current
   place. Colours come from the portal kit tokens (--app-*, portal.css), which
   take the accent from the MudBlazor palette, so the help takes on each
   organization's theme; the fallbacks keep it readable without portal.css.
