/* Direction: "The Ledger Book", in its working register. The design documents are the
   book being read; the screens are the book being written in. Same paper, ink, and
   faces as docs/assets/docs.css. Dense, ruled, numbers in mono. Red means one of two
   things only: a quantity going out, or something that needs a person. The screens
   carry no explanation of themselves; that is written on the BuddyBot Labs page, next
   to a screenshot. No motion. */
