   GFA Directory — base stylesheet

   THE TOKENS BELOW ARE FALLBACKS ONLY. From Phase 4 the admin panel generates
   public/assets/css/tokens.css from the settings table, and that file is loaded
   BEFORE this one so its values win. Nothing here is the source of truth.

   Why a generated FILE rather than an inline <style> block: an inline block would
   force 'unsafe-inline' into the Content-Security-Policy for every page, for every
   user of the product, forever. A file keeps style-src at 'self'.
