/* ==========================================================================
   GoneFinder — document pages (help, privacy, terms, security, acceptable use)
   --------------------------------------------------------------------------
   These pages used to load a separate four-file suite (professional-ui-system,
   professional-components, professional-typography, professional-brand — 83 KB)
   plus 130-200 lines of per-page inline CSS with hard-coded #003366 navy and
   #ff8c00 orange. They looked like a different product from the app, and none
   of it responded to the dark theme.

   This file replaces all of that. It reads only from design-tokens.css, so the
   legal pages, the help centre and the registry now share one palette, one type
   scale and one header.

   Load order on those pages:
       fonts/inter.css
       fontawesome-subset.css
       design-tokens.css   design system (source of truth)
