Explain the randomized goals rules in-game#5364

When building a MAM (Make Anything Machine) for crystal shapes, it would help to have a place in the game that explains which kinds of shapes the random goals can ask for.

Right now, players have to look this up online, which feels awkward. Some players may not realize that the goals only use certain shape types. They may spend time planning for every possible case, and only find out what the goals actually ask for after their MAM is already finished.

An in-game explanation in the codex would save players time and make crystal MAMs easier to plan.
