/* ===============================================================
   ToolDuck — ad-blocker support notice
   ===============================================================
   A compact support card, bottom-right on a desktop and a bottom sheet
   on a phone. Colours, radii, borders and the focus ring all come from
   the site tokens, so it belongs to ToolDuck without redefining anything.

   It is NOT a modal and there is no overlay: nothing here covers the
   page, and nothing here can stop the visitor using it.
