/* ============================================================
   UDM v2 Design System  ·  udm-design.css
   Foundational tokens, typography, buttons, forms & utilities.
   Section-specific styles (hero, mega menu, panels, …) are layered
   on top of this vocabulary by the layout and home-page partials.

   Brand red (#D3000F) is the standout action colour site-wide.
   Seasonal themes override the --udm-* custom properties below
   (see udm-theme.* / the server-side theme engine); every rule here
   reads those variables, so a theme switch re-colours everything.
