/* Alert colours follow the issuers' own green-yellow-orange-red scales (USGS PAGER, GDACS); every use also carries the
 * word, in tooltips, badges and tables. Fire detections use their own magenta ramp (--f1 to --f4) so they never read as
 * an alert. Checked with the dataviz validator against the land colour in both modes. */
