Apologies if this is a stupid question, but since Voxatron is envisioned as being a fantasy console, are there any plans for its carts to have size limitations in the same way Pico-8 has, or will anything pretty much be fair game?

I believe there is a limit to how big the file size can be.
Don't remember what that is, but I had to deal with it when uploading
cart with lot's of music files in it.
