   Footer — element-scoped styles for the site footer

   Brand + tagline + social, two link columns, a (static) server-status card
   and a bottom bar. Shared theme tokens (the --qr-* variables) are defined in
   qubitrp.css and consumed here. Loaded after main.css / the inline styles,
   so these rules own the footer look.
