/* SF Housing Construction Tracker
   House style: ported from the user's analytical-chart system (design-style.md) - white
   ground, ink greys, one workhorse accent and a validated second accent, Archivo throughout
   with tabular figures. That system's blue/orange pair encodes "a share or count" vs. "a
   ratio of two things"; this subject has no natural ratio, so the role is re-read for it:
     --blue    the workhorse - the page's subject, the primary count -> under construction
     --orange  the secondary, less-common case                       -> permitted, not started
     --green   a third categorical accent (same lightness band)      -> completions / BMR share
   Never alternate blue/orange for variety - each always means the same stage.
