kami-blue/client ? reverse-engineered prompt

I want you to build a Minecraft Forge client mod for 1.12.2 that feels like a continuation of KAMI Blue. It should launch cleanly, have a simple in game settings screen, and make it easy to toggle client features on and off while playing. Keep it organized so the code is easy to understand and extend, and make sure it fits the way a modded Minecraft client usually works.

If anything is unclear, check the current Forge docs online and then fill in the missing pieces in a sensible way. I mainly want a working, polished client that compiles, runs, and is ready to be used as a base for adding more features later.
