/* reformr — design tokens
   The single source of truth for colour, type, spacing, radius and motion.
   Every component rule in reformr.css references these, never a raw value.
   Authored deliberately (see NOTES.md §1–2); the equivalent of hale's :root
   token block, minus the Webflow export machinery.
