   and it draws itself. On paper it prints lake lines with ink index lines. Inside a dark band
   (like .namefield) it reverses on its own, because the tokens are set on .topo and read the
   --lake / --ink / --paper of wherever it sits. To restyle one map, override a --topo-* token
   on that canvas. Keep it to the palette: lake, ink and paper. Copper only marks the pin.

   Courier Prime set in a paper gap on the index lines, like a USGS quad. */
