SeyfertLocale

The `ctx.t` / `client.t(...)` accessor type. Kept as a named alias so that inferred return types (BaseClient.t, the context `t` getters, ...) emit a reference to `DefaultLocale` instead of eagerly baking it to `{}` at build time (where `SeyfertRegistry` has no `langs`), which left consumers with an untyped `ctx.t`.

export type SeyfertLocale = __InternalParseLocale<DefaultLocale> & {    get(locale?: string): DefaultLocale;};
