/* cryptopoints.co 1.0.0: "a folio on registry stone".
   Calm, exact, governed: one sheet per page on a stone ground, a garnet double margin rule as on ledger paper,
   Brygada 1918 for headings, Atkinson Hyperlegible Next for text, Atkinson Hyperlegible Mono for ledger figures only.
   No JavaScript. One motion: the conversion posted once in the home diagram (none under reduced motion). */
