Build instructions (upstream toolchain; not a claim of bit-for-bit reproduction)
1. Extract stockfish-js-93c9945-source.tar.gz.
2. Copy nn-9067e33176e8.nnue into the extracted src/ directory.
   Do not rely on `make net`: the lite net target is intentionally a no-op.
3. Install/activate Emscripten 3.1.7 per the source README, with Node.js,
   Python, make and the supporting Emscripten toolchain on PATH.
4. From the extracted source root:
     node build.js --lite --single-threaded --strict-em-check -f
   Consult that pinned source README/build.js for platform setup details.
5. Keep the generated .js and matching .wasm together and preserve these
   source, network and license downloads when distributing binaries.

The npm distribution itself contains the build used by this app. Its published
binary is verified against the pinned npm package; a source rebuild has not
been performed in this workspace. This file does not claim reproducible-build
attestation or legal advice.
