   Ground: cool bond paper. Ink: near-black, blue cast. One stamped ink blue,
   which owns the measurement gutter rather than being scattered as accents.
   Source Serif 4 carries every word. Azeret Mono is reserved for measurement:
   figures and dates. It is never used as decoration or as a label style. */
