   Top navigation - sticky bar of --nav-height

   Fully opaque background. An earlier version used 88% opacity +
   backdrop-filter blur, which let content show through during fast
   scroll - visually jarring, and on Chrome/Safari the backdrop blur
   can lag a frame behind the scroll position, flashing unblurred
   content past the nav. Opaque removes both issues; the visual
   frosted-glass effect was pretty but not worth the scroll flicker.
