/* =========================================================================
   Dispatch Tracking System — design tokens
   Palette: steel slate base, teal-blue primary, amber accent (stamp/tape),
   status greens/ambers/reds tuned for at-a-glance triage.
   Signature element: status pills styled like rubber dispatch stamps,
   ledger numbers set in monospace — nods to the physical GRN-stamp process.
