   IRIS — design tokens + component styles
   The "Assembly Mills (AMOS)" visual language: warm cream ground, flat
   white cards, rust accent, earthy data palette. Source of truth for the
   IRIS front end. See docs/design/BRAND.md.

   Framework-agnostic plain CSS — works on its own; Tailwind (see
   tailwind.config.js) maps these same tokens to utility classes.
