   A pen plotter's report: one ink, one green pen, hatching instead of tints, hollow marks instead of
   pale fills. Archivo (one variable family, width 62–125) does every job: expanded for the wordmark,
   normal for the text, narrow for data. Chart colors are validated with the dataviz palette validator
   against these exact surfaces. */
