/* Chart styles shared by index.html and progress.html.
   Chart colors were checked with the dataviz palette validator:
   done/progress pass CVD + normal-vision separation in both themes (light progress
   is under 3:1, so every chart that uses it also has a legend, labels and a table);
   the era ramp passes the ordinal checks (one hue, monotone lightness, light end >= 2:1). */
