   FixyPrompt public site.

   Colour tokens are copied from fixyprompt_app/lib/core/theme/app_colors.dart so the
   site and the app are recognisably the same product. If a brand colour changes there,
   change it here — these are the only two places any FixyPrompt hex lives.

   No web fonts are loaded. A font request to a third party would be a data disclosure
   the privacy policy would then have to describe, and the system stacks below already
   render Arabic and Latin well on every platform the app targets.
