`G.EXE` is built from `src/g.cpp` and `src/dosnet.h` plus the mTCP library sources (`TCPLIB/`, `TCPINC/` of the mTCP source archive,
shipped in `dev/dosllm-dev.zip`). `src/build.sh` shows the exact compiler options, `src/make_image.sh` assembles the boot floppy and
`src/build_assets.py` packs it into `assets.b64.js`.
