As I'm writing out my solution for this, I'm almost wondering if it's
time for the refactor I've been Theoretically Planning Someday, to move
items to a real `ItemAppearance` model in the database similar to
`PetState`… Hmm hmm hmm…
For now though, I'm taking a break!
I forget, there was some tricky debugging about getting the fixtures
right, I think the previous commit doesn't *actually* pass from a clean
setting. Ah well, looks good now!
