/* ============================================================
   HL7 Resolution Agent — "Clinical Teal" visual system
   Grounded in clinical-dashboard UX research:
   - one calm teal→cyan accent (trustworthy, medical)
   - amber = open/needs-attention, green = resolved,
     red RESERVED for genuine errors (avoids alarm fatigue)
   - WCAG AA contrast; never color alone (dots + labels)
   Dark by default; light theme via prefers-color-scheme.
