   Chart tokens live beside the app tokens so light and dark swap in one

   (blue/orange/aqua/yellow); the dark column is the same four hues stepped
   for the dark surface, not an automatic flip. Every chart also ships a
   visible value label — three of the light steps sit under 3:1 on white,
   so the label IS the accessible encoding, not decoration. */
