   Committed dark design: the map carries a dark basemap so that bright ramp
   steps read as "high volume", and mixing light chrome against a dark map
   reads worse than either alone. Tokens below are the data-viz reference
   palette's dark column; the two sequential ramps are validated
   lightness-matched (see build notes in README).
