   ACD Commerce Cloud: design system
   One stylesheet for the public site, customer portal and owner console.
   Rules for integration with the PHP brain:
   - No inline styles or scripts anywhere (brain CSP: default-src/style-src 'self').
   - Colours come only from the tokens below; components never hard-code colours.
   - Motion is decorative and switched off for prefers-reduced-motion.
