   Tokens are three-layer: primitive -> semantic -> component.
   Every primitive colour is taken from the shipping iOS app, not invented here:
     --c-green-*   AccentColor.colorset (light / dark appearance)
     --c-orange-*  the .orange tint the app uses for "waiting for approval"
     --c-icon-*    the AppIcon gradient stops
     --c-kid-*     the eight KidColor cases
