/* ======================================================================
   TRADER LIGHT/DARK THEME CONTRACT — FINAL

   Purpose:
   - Replace runtime color dependence on settings/skins/skins.json.
   - Preserve the currently effective Classic Business light appearance.
   - Define a complete dark token set, including bridge-only variables.
   - Keep the existing --skin-* names as a compatibility contract while the
     legacy frontend is migrated gradually.

   Runtime note:
   - Dark is the default when no persisted preference exists.
   - Persisted Light/Dark selection is restored before first paint.
