A Fleet card warns Low fuel when the tank can't fly the ship's longest
leg to a discovered place; the fuel sheet lists Manual first as the
default (decisions 0.5.112, 0.5.113).

Ship cards show a fuel gauge and refuel policy, with a Fuel sheet to
fill or buy an amount, switch policy, and order emergency fuel when it
is offered. The dispatch sheet and deadhead picker show fuel needed,
on board and left after, price fuel at the tank's average, and offer
"Refuel here first". Locations show fuel prices with the cheapest
marked, and delivery summaries list Auto top-ups.
