   C&S AIR PRODUCTS — PROJECTS
   Extends styles.css. Reuses the design tokens (colors, type,
   spacing, radii) defined in :root there. Shared by
   projects/index.twig (overview grid) and projects/_individual.twig
   (single project detail).

   Mobile-first: unqueried rules below are the small-screen
   (< 768px) styles. min-width media queries layer up:
     @media (min-width: 768px)  → tablet and up
     @media (min-width: 1200px) → desktop only
