/* ==========================================================================
   Brand Assessment - shared design system
   Owned by the survey, imported by the dashboard.

   Rules for this file:
   - Never write a literal color. Every color resolves from a custom property
     that is injected on :root at runtime from client.config.json.
   - Survey-only layout is namespaced with .survey so dashboard classes in
     admin.css never collide.
