Drop-in copy of C:\Users\maj00r\Projects\maj0sted-master minus its web/ directory - the WASM frontend is not being ported, the editor drives the same C++ API natively. What is left is plain C++20 with no dependencies: domain model (niweleta, plan and profile geometry, fitting, parallelism), project serialization, rail sampling and the editor document. src/web/ribbon.cpp was missing from the library source list; added, since without it the ribbon symbols never make it into the archive.
