   Brand tokens come from the design system (Ink / Cloud / Mist / Fount Blue /
   Ember / Slate; Plus Jakarta Sans + Inter + IBM Plex Mono; 10px buttons).
   Craft layer follows Apple's design principles: instant press feedback,
   size-specific tracking, translucent materials, spatial consistency,
   and reduced-motion / transparency / contrast support.
