1/**
2 * Pack the command-line bundle as an npm tarball and put it where the page is
3 * deployed, so that
4 *
5 * npx https://concept-collection.github.io/turing-surface-cache/fill.tgz
6 *
7 * installs and runs it anywhere node is. Nothing is published to the registry:
8 * npm installs a tarball from a URL as happily as from a package name, and
9 * this way the command line is always the same commit as the page it fills the
10 * cache for.
11 *
12 * The package.json written here is the whole published manifest. It has no
13 * numbl dependency — the compiler is bundled into fill.js exactly as it is
14 * into the page — and its only real dependency is h5wasm, whose node build
15 * reads its wasm off disk and so cannot be bundled. Dawn is optional, so the
16 * install still succeeds on a machine that has no prebuilt binary for it; the
17 * CLI says what to do about that if it comes to it.
18 *
19 * Usage: node scripts/pack-cli.mjs (after `vite build --config vite.cli.config.ts`)
