You are developing a web app that is a clone of MatterControl's design tools. MatterControl is a C# 3D modeller and slicer. You are only cloning the 3D design tools, not the slicer/printing capabilities.
Your task list is in @TODO.md.
The source code for the original program, MatterControl, is in the `original` directory. Technical research on the MatterControl codebase can be found in the `research` directory. See @research/index.md for an overview.
Remember to use `nix-shell` to grab temporary tools as needed.
