/* =========================================================================
   Meridian HMS — design system

   Written as tokens first, components second. The palette is a clinical teal
   against warm greys: high contrast for dense tables, calm enough to sit in
   front of for a nine-hour shift. Light and dark are both first-class; dark is
   a token override, not a second stylesheet.

   Type is the system UI stack on purpose — a webfont would be another 90 KB on
   a connection that may be a rural 3G tether, and this system has to work
   there.
