   The page borrows the vernacular of the documents this audience reads every
   day: the information memorandum, the tombstone and the term sheet. Content is
   set as records with labelled fields and hairline rules rather than as
   decorated cards. One accent (brass) carries emphasis; everything else is
   navy, graphite and cool paper.
