   No webfont: a self-hosted family would eat most of the 50 KB budget and add
   an HTTP request, and this is a data tool, not a brochure. System UI faces
   instead, with tabular figures wherever money appears -- in a ledger, digits
   that line up column-wise matter more than digits with personality.
