/**
 * The command line's bundle: the same source as the page, built for node.
 *
 * Everything under src/ is bundled in, numbl's compiler included, exactly as
 * in the page's build — the published package therefore has no dependency on
 * a numbl checkout. What stays external is what cannot be bundled: h5wasm,
 * whose node build reads its wasm off disk, and Dawn, which is a native
 * addon (and optional, so a machine without it still installs).
