/* Mercatoria: "Chart and Charter".
   The site alternates two materials. The sea chart (navy, rhumb lines, routes) carries movement and capital.
   The charter (vellum, ruled measure, plates, seals) carries rules and trust. A single route line threads
   down the margin from one port of call to the next. Platforms re-skin the same system through tokens. */
