   Data views: the case brief, the coverage heatmap, the ownership and
   people network, the dashboard's KPI strip and list-age meters, the mini
   coverage bars and stage segments.

   Signal colours are status colours: reserved meanings, never series colours,
   and always with an icon or words. Only red flags (red) and finished work
   (green) carry colour; pending, gaps and "nothing recorded" are steps of
   the neutral ramp.
