/* ============================================================================
   Site header — utility bar, primary nav, mobile drawer.

   Two states, driven by header.js adding .is-stuck past the hero:
     • at rest  — transparent over the hero, white type, no shadow
     • stuck    — solid paper, ink type, hairline + shadow

   Pages without a hero opt out by setting .site-header--solid, which pins the
   stuck appearance from the first paint. Without that, the nav on (say) the
   contact page would render white-on-white until the visitor scrolled.
