   - Minimal reset (Josh Comeau-ish) so demo pages don't inherit browser
     defaults and don't need a full reset.scss.
   - Layout helpers, buttons, chips, cards that biz AND admin demos
     both use.
   - IMPORTANT: applies to .demo-theme-biz and .demo-theme-admin bodies;
     relies on the neutral --demo-* aliases from tokens.css (load that
     file BEFORE this one).
