This project uses `emscripten 3.1.7` via Docker. You will need a working `docker`
install to build the Emscripten artifacts.
This project uses `emscripten 3.1.32`.
- On ARM64, you should install `emscripten` on your machine. For example on macOS, `brew install emscripten`.
- If _the correct version of emcc_ is not in your PATH, compilation falls back to using Docker.
On ARM64, this is 10-50x slower than native compilation, but it's just fine on x64.
