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.

Export save turns the whole save into one code (gzip + base64url
behind a DEADHEAD1. prefix) to copy or share as a file; Import save
takes a pasted code or a file, migrates and validates it, and replaces
the company after confirmation. A bad code is refused and changes
nothing. These replace the backup code. Debug info now gives the save
id, save version and storage type.
