/* ERD web design system: components, surfaces and motion.
   Requires erd-tokens.css (and erd-fonts.css for Montserrat) loaded before it.
   Everything is plain CSS with no build step. Class names are prefixed only
   where a clash with a host theme is likely; the rest match the client portal
   so the two stay in step.

   Sections: base, atmosphere, the mark, motion, brand furniture, controls,
   surfaces, messages, badges, tabs, dashboard shell, responsive, reduced motion. */
