/* ==========================================================================
   ShipTracking — design system
   Vernacular: the waybill / manifest / customs stamp. Tracking codes and
   timestamps are set in mono (as they'd appear on a real printed waybill),
   headings use a condensed industrial display face, and the one moment of
   flourish is the "delivered" ink-stamp badge — everything else stays quiet.
