   Subject: clinical / hospital operations software used by reception,
   pharmacists, doctors and administrators under time pressure.
   Direction: "clinical instrument panel" - precise, calm, legible at a
   glance, with a single signature motif (the pulse line) tying every
   screen back to the hospital domain without leaning on a red cross
   or generic medical-blue cliche.
