/* How the sky dates a tablet. Parchment written in ink. Colors are tokens.
   Titles are set in IM Fell English; text, labels and figures in Roboto, as in the specforge showcase.
   Each clock has its own ink, checked with the dataviz palette validator on this parchment (all
   pairs, normal and color-blind vision): Mars red, Jupiter purple, Saturn gold, lunar eclipses blue,
   the solar year green. Iron-gall ink marks the years that every clock so far allows, gold leaf the
   strict set, and a red seal the published year, which comes last. */
