// A WASI host, so the acceptance table can run a wasm32 build without a
// wasmtime or wasmer being installed. Node has had node:wasi since 16; it is
// still flagged experimental, hence --no-warnings at the call site, and before
// Node 20 it needs --experimental-wasi-unstable-preview1 as well. The
// acceptance test probes rather than assumes: if this file cannot run the
// module, the wasm case is skipped with what went wrong.
//
// preopens is empty on purpose. sand-headless reads nothing and writes one
// line to stdout, which is the whole point of it being the cross-target case.
