   The eight rules this file obeys, from ledger-system.html s08:
     01  serif carries meaning, sans carries machinery
     02  square corners, no exceptions
     03  one green per view
     04  rules instead of boxes
     05  numbers tabular and right-aligned
     06  running text stops at 66 characters
     07  no gradients, no shadows, no rounded cards
     08  voice rules still apply
