/* ===========================================================================
   Pilot logbook — a sheet of the chart, ruled like a paper logbook: columns,
   tabular numerals, a rule under each month, a double rule under the totals.
   Tokens only (tokens.css); the grid is shared by head, rows and totals so
   every column lines up. Below 640 px the columns fold under the route.
