Venus Cloud City, Io Sulfur Works and Europa Ice Station join the map
(fixed positions, Io and Europa riding with Jupiter), with their
fuel prices, range factors, shippers and sprites. Each makes a
Standard good so boards work there. The first-purchase balance window
widens to 45-95 minutes (user decision).

Ships carry fuel: a leg burns from the tank at departure (no credits),
dispatch needs the fuel on board (not-enough-fuel), a leg's fuel cost
is fuel burned x the tank's average price, and Auto top-up refills on
landing with what the credits cover. The save gains tank fields (save
version 2, migration fills every tank). Market ships arrive full; the
deal's ships come with a quarter tank to keep the balance targets.
