/* CameraDiet marketing site.
   Tokens mirror the Flutter app (lib/common/styles/colors.dart) so the site
   and the product read as one brand.

   Colour rule, carried over from the app: light green is for SURFACES —
   backgrounds, cards, chips, calm sections. Orange is for ACTIONS and energy —
   primary buttons, calorie cues. The two families are never blended into a
   single fill. */
