   SFamily — marketing site
   ---------------------------------------------------------------------------
   Layout: a single dark column on the app's own top-to-bottom wash, with
   content held in glass panels. One bold moment only — the shield gradient in
   the hero — and everything else kept quiet around it.

   Every colour below is lifted verbatim from the app's single source of truth,
   lib/core/theme/app_colors.dart. If a value changes there, change it here;
   a landing page that is nearly the brand colour is worse than one that is
   obviously a different colour.

   Deliberately single-theme. The app has no light mode, and a light version of
   this page would be a different product.
