Campaign

mass pays for ships and mines · relics unlock the frontier — earned on deep runs and at relic sites

pick the mine to haul from — further out is richer and more dangerous. Cargo hauled sets the fight's difficulty.

pick the ships for the run (need a hauler + escorts). Ships lost in battle are gone for good.

permanent unlocks bought with relics ◆ — hull classes above the frigate, heavy tech, and the shipyard core (does nothing yet: it's the seed of the construction-platform era)

how the selected ships deploy — layer 0 holds the center (haulers anchor there), outer layers screen. Saved for every run.
