/* ==========================================================================
   Dispatch loading tool — industrial/utilitarian styling
   --------------------------------------------------------------------------
   Design intent:
     - Dense information display: this is a working surface, not a marketing
       page. Loading staff scan lots of rows quickly.
     - Monospace for identifiers (Pro#, route codes, zips) so they line up
       and misreads are obvious.
     - Status conveyed by color AND symbol (no color-only encoding).
     - High contrast, dark theme: looks correct under warehouse lighting and
       on shared monitors at a distance.
