Membercat-Studios/ModelShifter — reverse-engineered prompt

Build me a Minecraft Fabric mod called ModelShifter. I want it to let players change how all player characters look on their own screen only, so it works on any server and does not affect other people or gameplay.

The mod should add a simple model selection screen that can be opened from a purple button in the Minecraft options menu. From there, I should be able to pick a custom player model or turn the feature off. Include several fun preset models like a cat, ghast, armadillo, frog, enderman, chest, crab, dinosaur, baby, flat player, square, and Among Us style character. The chosen model should replace the normal player model visually for myself and other players, but only client side.

Make it for Minecraft Fabric around versions 1.20.6 to 1.21.1, using GeckoLib for animated models if needed. Keep the setup ready to build with Gradle, and look up current Fabric and GeckoLib docs online if you need to.
