   NIMBUS × APPLE — Portal Design System (aligned to clinical v3)
   Parchment canvas · white hairline cards · flat #0066cc · Open Sans.

   Token block mirrors the canonical source of truth:
   VetOS.Server/wwwroot/nimbus.css (Nimbus × Apple v3). Keep the :root values
   in sync with that file; portal-only component classes below consume the
   tokens and re-implement the portal's .nim-* vocabulary on the v3 rules:
   single --shadow-product on elevated surfaces only, no glow shadows, no
   hover-lift transforms, weight ladder 400/600/700 (never 500).
