   ---------------------------------------------------------------------
   Design note: this screen is watched for eight hours at a stretch by a
   dispatcher, so it is built to be read, not admired.

   The colour system is lifted from the one artefact everyone in this
   workflow already reads by colour — the vacutainer cap. Lavender EDTA,
   red serum, grey fluoride, blue citrate, green heparin, yellow urine.
   Status and sample type share that vocabulary, and every row carries a
   4px "cap spine" on its left edge so the board scans like a tube rack.

   Everything identifying — order numbers, barcodes, coordinates, ETAs —
   is set in tabular monospace so digits line up down a column and a
   wrong one stands out.
