   The mark specs are deliberate and worth keeping: bars capped at 24px so the

   square, a 2px gap of surface colour doing the separating instead of a border,
   and hairline solid rules. Series colours are not defined here — they come from
   ChartPalette, which is validated for colour-vision separation and shared with
