/* ==========================================================================
   charts.css — the look of the charts in docs/charts/, drawn by docs/js/charts.js.
   No chart library: each chart is plain HTML or SVG, so it is on screen as soon
   as the page is.

   Colour does one job per chart:
   - one series        -> --one, the site red
   - a few named lines -> --c1 to --c6, a fixed order chosen to stay apart for
                          colour-blind readers; any line past the sixth is grey
   - how much (a map)  -> --s0 to --s4, one red from light to dark
   - a state           -> --good / --warn / --bad / --none, always beside a label
   Dark mode has its own steps rather than an automatic flip.
