/* Palette taken verbatim from the app's design tokens (lib/src/design_system/
   tokens.dart) so the site and the App Store listing read as one product.
   Dark is the brand home — the app icon is a near-black plate with a lime
   accent — so dark is the default and light is the explicit opt-in. The lime
   cannot be used raw on light surfaces (about 1.2:1 against white), which is
   why the light palette carries a deepened olive instead. Every pair here is
   the app's, and the app's are contrast-tested. */
