  Tokens follow the reference data-viz palette (validated with the palette checker):
  chrome/ink, two series (blue, orange) for counts, seven categorical day colors
  (passes the colorblind checks; contrast relief = legends, tooltips and the table),
  red for the mainshock, gray for the week before, status colors for the live pill. Intensity uses the USGS
  ShakeMap scale (set in js/intensity.js). Dark mode has its own validated steps.
