/* The site's charts (Components/Charts). Colours do one job each: categorical slots for what a series is (fixed to it,
   never to its rank), a blue ramp for how much, and the site's success and danger inks for a change. The categorical
   slots and the ramps were checked against the skins' panels (CVD separation, lightness band, contrast): on the lightest
   panel slot 6 drops under 3:1, so every chart has a table view. Marks are thin: columns at most 24px with 4px rounded
   tops, 2px lines, a 2px gap between touching fills, hairline solid grid. Text never wears a series colour. */
