/* Homer.
   The page is built on one idea: speech is messy, state is exact.
   Left column is set in a humanist sans and behaves like talk. Right column is
   set in mono with tabular figures and behaves like a ledger. The whole product
   is the arrow between them, so the typography carries it. */
