/* AI Incident Register
   Layout: masthead, indicator row, map with its time control beside the
   rankings, the period curve, a record-quality strip, then the filterable
   register and the method. Three semantic colours for the provenance classes,
   a separate ramp for the choropleth, one accent for anything interactive. */
