margaretmilot36004115132/Voil-Client ? reverse-engineered prompt

Build me a Minecraft 1.21.1 client mod called Voil that feels polished and easy to use.

I want it to have two modes, a quiet ghost mode and a stronger hybrid mode, with a simple in game way to switch between them. Make the client focus on PvP and general quality of life, with sections for combat, movement, player tools, visual tweaks, utilities, and bypass related settings. It should run on Fabric for 1.21.1 and be set up so I can drop it into the mods folder and launch it normally.

Please make the interface clean, modern, and lightweight, with sensible default settings, clear toggles, and good performance. Add smart targeting style options, configurable module settings, and anything else that helps it feel like a serious competitive client. If you need to check current Fabric or Minecraft 1.21.1 docs, look them up online first.
