/* ============================================================
   Shared site nav (.nav-wrap) integration with the editor shell
   ------------------------------------------------------------
   /assets/pill-nav.css makes .nav-wrap position:fixed (correct
   for the marketing site). Inside the editor we keep it IN FLOW
   (sticky) so gallery/editor content is never hidden beneath it,
   and we tint it to match the dark UI. The `html ` prefix raises
   specificity above pill-nav.css so these win regardless of load
   order; pill-nav.js leaves the editor's own nav links intact.
