Every building needs a planet-hazard material bundle on top of its normal
BuildingCosts (SEA for low pressure, HSE for high pressure, MGC for low
gravity, BL for high gravity, INS for cold, TSH for heat - area-scaled
where applicable), confirmed against live in-game build panels on Nike.
FIO's own BuildRequirements field is an unreliable superset across hazard
types, not a direct per-building list - don't use it directly.
- puga/planet.py::environment_extras(): the real threshold table.
- tools/buildcost.py: full construction material list for one building,
optionally on a given planet.
- Wired into whatif.py/buy.py (via simulate(planet=...)) and scan.py's
own bcost(), so their capex numbers stop silently omitting this.
- docs/mechanics.md: the rule, plus a separate forum-sourced note on the
CX order-cancellation penalty.

Ranks every planet with a given extraction factor using FIO's bulk
planet data, pricing founding cost straight from FIO's own
BuildRequirements (real environment-extras materials for that specific
planet, not guessed temperature/pressure thresholds - PRUNplanner's own
calculations don't model those either). Takes --from an existing base
to report jump distance via tools/route.py, since pure-factor ranking
alone is misleading: the best-factor planets found for FEO were all
500-2600+ ly away, confirming Vulcan (merely decent factor, same system
as Deimos) was still the right practical pick.
