   C&S AIR PRODUCTS — SUPPORT
   Extends styles.css. Reuses the design tokens (colors, type,
   spacing, radii) defined in :root there.

   Mobile-first: unqueried rules below are the small-screen
   (< 768px) styles. min-width media queries layer up:
     @media (min-width: 900px)  → two-column layout kicks in
