   Component styles for the Contact page's nx- widgets (Let's Talk channels +

   page (see nexus_home_assets() in nexus-homepage.php) — everything here
   reads from tokens.css custom properties, same discipline as
   nexus-homepage.css. Shared primitives (.nx-container, .nx-eyebrow, .nx-h2,
   .nx-btn, .nx-section-head) live there and are reused as-is, not redefined.
