Now I want to add a bunch of vanity designs for balls.
I could add them, each of them, as new piece styles. But that's a lot of styles just for a different ball decal. And that conflicts with the idea of having one foil pack per one style of a piece. Because I want these vanity designs to come in a pack together.
As I don't want to rework a lot of systems just to support this approach, I was trying to come up with a way to have one new style, a vanity style.
