- Fix the bundle filename (sunk-enland -> sunken-land) across the manifest,
  build config, demo and docs.
- Wildcard the subpath exports so every preset (including reactions.css) and
  the sticker set are importable.
- Publish metadata: version 0.1.0, MIT license, repository/homepage, public
  access on npm.pkg.github.com, prepack build, files allowlist.
- Guard the custom element registration so importing the package on the
  server (Nuxt/Nitro SSR) is a no-op instead of a crash.
- Tag-driven publish workflow (GITHUB_TOKEN, packages: write) that
  type-checks, runs the browser suite and verifies the published install.
