It exports STL for printing and glTF/GLB scenes with TOML-defined PBR materials for visualization. The engine is a C++ core with Rust bindings, a manifold geometry engine delivering watertight meshes. The workflow emphasizes tests and linting (cargo test, cargo clippy) and strong typing to prevent mistakes....
