CadFreely changes two Emscripten binding code generators into equivalent
ordinary closures to support a Content Security Policy without unsafe-eval.
The modification and reproducible asset-copy procedure are in
scripts/prepare-brep-assets.mjs. Native WASM code is copied unchanged.

This runtime is loaded only when modeling is requested. Exact BREP data is
retained; display triangles do not replace the solid's topology or geometry.
STEP output is available. ACIS/SAT conversion and native DWG/DXF solid export
are not supplied by this component.

The wrapper's MIT license does not supersede the embedded libraries' licenses.
License/source evidence is not legal clearance for the combined application.
