Per seed recipies

Your world seed decides how crafting works. As the world loads, the mod swaps ingredients between recipes that share the same grid shape, so a pickaxe or a bed may want something completely unexpected while everything stays craftable. Every seed produces its own set of rules, and the same seed always produces the same ones, so you can hand a friend the seed and they get exactly the puzzle you got. Nothing is random once the world exists, and nothing needs configuring.
