The no-strand rule now asks whether the ship could leave the
destination on a full tank where fuel is sold, or on what is left
after the leg where it isn't. Emergency fuel is offered to an idle
ship that can't reach anywhere when the player can't afford the
shortfall: the cheapest leg's fuel at 2.5x the local price.

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.

Ships get a tank capacity and a burn rate instead of range and fuel
cost; locations get a fixed fuel price and a sellsFuel flag instead of
the launch cost multiplier. A leg burns burn rate x the economic
distance of (distance / origin factor), and reach is a full tank's
worth. Tanks are sized so every reach answer is unchanged.

Positions, distances, range checks, trip times, fuel and the no-strand
rule no longer take a time argument; the 48-hour no-strand margin goes
with it. Tests now check that a route's pay, trip time and fuel are the
same whenever it is offered or flown.
