Locale aliases (uk, fil/tl, zh-hant, legacy in→id) with fixed browser/CLI/cookie detection; config/i18n.json shipped in the npm package; duplicate 'in' locale retired (42 honest locales); real-translation ratio gate with ratchet baseline (advisory); add-locale orchestrator + shared libs (batched translation backend, config-generated language bars, run-translation --adopt/--targets-only, scaffold helpers); tests derive the locale count from config with surface parity guards; docs and every public locale-count claim aligned.

* Resolves a locale requested via cookie (`NEXT_LOCALE`) or the `x-locale`

* header to a configured locale. Accepts declared aliases so a cookie written
|
|
* before a locale was retired (`in` → `id`) or a bare tag (`uk` → `uk-UA`)
|
|
* keeps working. Dependency-free: shared by `request.ts` and unit tests.
