/* Elegant minimal, mobile first. One warm accent, serif display type, hairline
   rules instead of boxes, and tables that become cards on a phone.

   Chart colours are a single-hue ordinal ramp (--c1…--c8) rather than a set of
   categorical hues: "where the money goes" is ordered magnitude, so one hue
   stepped light→dark reads correctly and stays calm. The ramp is validated for
   monotone lightness, adjacent-step separation and contrast against --paper. */
