   Loaded AFTER monolith.css and monolith-fx.css.
   The hero is dark + atmospheric; this carries that world all
   the way down instead of slamming into light paper. It only
   re-points the existing palette tokens + patches the few
   places that hardcoded the old paper color. Delete this one
   <link> to fall back to the original light Monolith.
