/* The spread-chart key (.dist-note, .dist-legend, .dist-swatch--range
   / --ramp / --median) lived here. It went with the chart it labelled
   when both cities-page charts were removed on 2026-09-23 (UAT). The
   only chart left on the site is the per-city histogram on city.html,
   which is why this file is now four rules long. */
