/* ============================================================
   TA Desk — shared design tokens
   One palette for every TA job on this site. Derived from the
   Rock Your Baby stress scale: calm (indigo) -> panic (amber-red).

   Every page loads this file FIRST, then its own stylesheet.
   The per-job stylesheets define no colours of their own; they
   alias these tokens, so re-theming the whole site is one edit here.
