/* Cenvistone Catalogue — design system.
   ---------------------------------------------------------------------------
   The brand colours come from /theme.css (--color-primary, --color-accent and
   their automatic contrast colours).  Everything else is derived here so that
   an admin can change the brand without touching a line of markup.

   Rules of the house:
   - no inline styles and no inline scripts (strict CSP),
   - every colour is a token, every spacing a step of the scale,
   - the layout works from 320 px up to 1600 px.
