   Camonsoft UI — Design System layer
   Minimal, neutral, professional. Loaded AFTER output.css (Tailwind).
   Plain CSS (no build step) so it is safe for the Railway deploy.

   Conventions:
   - Design tokens live in :root as --cms-* custom properties.
   - Reusable components are prefixed .cms-* and can coexist with Tailwind
     utility classes already in the templates.
   - Accent (brand blue) is used sparingly on a neutral base.
