MCRcortex/voxy ? reverse-engineered prompt

Build me a Minecraft mod called Voxy that makes distant terrain render in lower detail so the game runs smoother, especially when looking far into the world.

I want it to feel like a real mod players can drop in and use, with the main focus being better performance without making the game look broken. Keep the experience simple, make sure it works cleanly inside Minecraft, and include any basic settings a player would expect for turning the feature on or adjusting how it behaves. If you need to check current modding docs or APIs while building it, go ahead and look them up online.

Please make it solid, well organized, and ready to run as a normal Java Minecraft mod.
