/* =============================================================================
   SFSocial site styles

   Design tokens are lifted directly from the Flutter app so the site and the
   product read as one thing:

     app/sfdating/lib/app/theme/app_colors.dart      colour tokens
     app/sfdating/lib/app/theme/app_gradients.dart   brand / hero / glow
     app/sfdating/lib/app/theme/app_text_styles.dart Plus Jakarta Sans + scale
     app/sfdating/lib/app/theme/app_theme.dart       radius 18 / 16, elevation 0
     app/sfdating/lib/app/theme/app_glass.dart       blur sigma 14

   Two deliberate deviations from the app, both for contrast. Documented at the
   token so nobody "fixes" them back:
     - CTA gradient is deepened in light mode. The app's #F03E3E carries white
       text at 3.81:1, under the 4.5:1 floor for the button's label size.
     - CTA ink flips to near-black in dark mode, where the light red gradient
       cannot carry white text at all (2.80:1).
