/* The root pill carries backdrop-filter; because the dropdown panel is a DOM
   descendant of .nav-pill, that ancestor filter forms a backdrop root and the
   panel's own backdrop-filter has nothing left to blur (page shows through
   sharp). Move the pill glass to a ::before layer (a sibling, not an ancestor,
   of the panel) so .nav-pill is no longer a backdrop-filter ancestor and the
   panel blurs the page exactly like the pill. */
