   Basket badge, slide-out drawer and return banner.

   Shared by every page that sells something (the home page, the sponsorship
   hub and the four category pages) and
   deliberately written against the brand custom properties already declared in
   each page's :root, with literal fallbacks so a page that drops one still
   renders sensibly.
