/* =============================================================
   AVDI USA — Service Page Shared Styles
   
   ARCHITECTURE:
   - styles.css defines design tokens (light mode defaults)
   - This file handles service-page layout + the ONE dark
     exception: the hero (always dark, driven by overlay).
   - Content sections (overview, features, use cases, related)
     use the default LIGHT tokens — white/slate backgrounds,
     dark text — matching the homepage content section feel.
   - CTA band is always blue (inline override).
   - Footer inherits from styles.css .footer (black).
   ============================================================= */
