     ::after     black tint + sheen       — every browser
   Two rules this structure exists to satisfy:
   1. The bar itself must carry NO filter. An element with backdrop-filter
      becomes a "backdrop root", which would limit .nav-glass to sampling only
      the bar's own paint — leaving it nothing but flat tint to distort.
   2. Blur and url() must live in separate declarations. Safari claims support
      for url() in backdrop-filter but renders nothing for it, so a combined
      declaration loses the blur there. */
