/*
 * Results explorer (static/js/explorer.js): quality or speed against cost, by method family.
 *
 * Colours, radius and widths are the shared tokens from index.css, and the button groups follow
 * the dark pressed state of the comparison player in compare.css; the "Compare with" toggles,
 * which add families rather than pick one option, are check boxes instead. Method colours come
 * from the data file and reach the legend and table through --ex-method. explorer.js sets
 * --ex-move (the time the points take to glide to a new selection), --ex-fade (the axis
 * cross-fade) and --ex-tip-columns (values per row of the compact tooltip), and adds .is-static
 * while it draws without animation.
