+The CLI binary carries every module and may grow to hundreds of MB; a library imports only what it uses, as it imports any dependency, and nothing is fetched at run time. Goal 2 says what ships where. The maintainer decided on 2026-10-04: one module per locale, one per country's `geo/` tree and one for `misc`; and a library passes a module to `New`, `New(WithData(svse.Data))`, with no registry a module's import fills, per the technical principles' dependency injection and no package globals. Before the module API ships, a panel of the README's audience personas tries pulling in data with it.
