/* The crash map's own rules on top of the Proactive Health AIO kit (kit/css, the 1.3.0 export from when it was called dayring).
   The shell (menu, head, About dialog) follows the Ready to Train? web version. Data colours were checked with the dataviz
   validator: the hex ramp is one hue, lighter to darker on the light map (more crashes = darker) and the other way
   round on the dark map, each step clearly apart and the faintest step at least 2:1 against its basemap; the two
   "higher / lower than Victoria" colours pass the colour-vision checks in both modes. */
