   Extends styles.css. Reuses the design tokens (colors, type,
   spacing, radii) defined in :root there, and the shared .expert
   / .value-prop__label CTA component also defined there.

   Mobile-first: unqueried rules below are the small-screen
   (< 768px) styles. min-width media queries layer up:
     @media (min-width: 640px)  → tablet and up
     @media (min-width: 900px)  → sidebar layout kicks in
     @media (min-width: 1200px) → desktop only
