trade is a menu for buying and selling goods acquired during travel.
Items are split into colour groups
red for space suits and logistics drones
blue is crew, the only free item
orange is engine, loaders and other equipment.
Green is compost
Each item in a colour group is affected by the same price changes. prices change between every new visit I.e once you leave the sector
some items, such as compost, which can be generated on the players ship, sell for more closer to the void. other items that can be created, such as ingots via smelting, always sell for the same price
