/* ---------------------------------------------------------------------------
   Load gauge.

   Every animated property here is transform or opacity, so the whole thing
   composites on the GPU and never triggers layout. That is what keeps it
   steady on a phone while the basket is being edited.

   Sizes are in cqi/clamp rather than breakpoints: the gauge sits in a narrow
   sidebar on desktop and full width on a phone, and should look deliberate in
   both without a media query for each host.
