   The single source of truth for every page in the site: colour, type,
   spacing, radius, shadow and motion tokens, plus the reusable component
   classes (chrome, buttons, cards, layout helpers) pages reuse verbatim.

   Mobile-first: base rules target small screens; min-width media queries
   progressively scale the layout up. No page should redefine these tokens.
