   so the panel opens below the visible area, and (b) `.vnav-sidebar`
   has `overflow: hidden`, which clips the absolutely-positioned panel.
   Portal them out to the viewport with `position: fixed`, anchored to
   the bottom of the viewport and offset to the right of the sidebar.
   Desktop-only — on mobile the panels use their own inset:0 full-screen
   modal path and the bell/badge don't live in `.vnav-footer` anyway.
