/* ============================================================
   charts.css — donut figures and their value tables.

   Colour comes entirely from the --fh-chart-* ramps in main.css (D-011: no hex
   outside main.css). This file is layout only.

   Every figure pairs the donut with a value table carrying the same swatches.
   That is not decoration: the light end of the day ramp falls below 3:1 on the
   card, and a visible label or table view is the required relief. Identity is
   therefore never carried by hue alone, and the figure still reads if the
   colours fail entirely.
