/* Design tokens — the single source of truth for the backoffice look.
   Values seeded from the palette that shared.css already used, so
   adopting a token is never a visual change by itself.

   THE CONTRACT: component CSS (backoffice/components/*.css) may not
   invent design values — every color comes from a var() defined here.
   Need a value that doesn't exist? Add a token HERE, then use it. Never
   a second token file: one vocabulary, extended, is what keeps the
   system a system. Enforced by scripts/checkDesignTokens.js (runs with
   npm test).

   Rule of adoption: new or touched code uses tokens; untouched code keeps
   its hard-coded values until its migration slice comes up. */
