   PackageTrackNow — Kinetic Logistics design system
   Ported by hand from ui/.../kinetic_logistics/DESIGN.md. No Tailwind.

   Note on radii: DESIGN.md's prose and the generated tailwind config disagree
   (config says lg=0.5rem, prose says "rounded-lg (16px)"). The prose is the
   spec of record, so: controls 8px, cards 12px, hero surfaces 16px.
