// version, with workspace:* specs rewritten to concrete versions.
//
// Unlike `release.ts --force-publish-all`, this does NOT touch unrelated
// workspace packages (fonts, demos…) and uses
// `npm pack --json` to publish the produced tarball directly (no fragile
// rename step). Idempotent: skips any name@version already on npm.
//
// Auth: relies on the npm registry config already in place (CI writes
// ~/.npmrc with the token). Run from the repo root.
