/* ============================================================================
   Quiet Green, on the web.

   The palette, type scale, spacing steps and the hairline rule come from the
   app's own system (lib/shared/app_theme.dart, written up in
   docs/design-system.html). No colour here is invented.

   Where this departs from the app, and why: the app is product UI, where the
   system's job is to get out of the way. This is a landing page, where the
   job is to be looked at. So the marketing bands use full-bleed colour,
   display-scale numerals and asymmetric composition, while the legal and
   support documents keep the quiet treatment. The system allows exactly this
   distinction: "Staggered entrances are for marketing pages."
