Calibrated from a controlled slider sweep across 5 real destinations, read from the live APEX Ship Flight Control DOM. Covers STL cruise, FTL jumps/charges, gateway hops (measured LOCK fees for ANT<->HRT/BEN), and per-planet landing fuel. Scoped to this account's one hull/reactor; open gaps (gravity dependence, hull generalization, gateway one-way links, per-gateway volume caps) are documented in the module docstring. tools/shiptrip.py is the simple entry point (ship + from + to, works out jumps/charges/landing itself); tools/shipcost.py takes explicit physics params for when the breakdown is already known. puga/route.py now also resolves CX station codes (ANT, HRT, ...), not just planets/systems - this was needed for the gateway-aware lookups to work at all.
