// start at Entity.StartingCellTemperature, so every shipped weapon must perform there, or a ship fitted with it
// can never fire it. The catalog comes from the shipped GameData/Aetheria.cc and the temperature from the
// constant Entity builds its cells with, so a unit slip in authoring (celsius for kelvin) fails here.
