Package reference
Localization supplies immutable policies, typed catalog IDs, bounded language negotiation, fallback metadata and native Intl formatting. React and Nest bindings can be adopted independently.
App UI and Admin UI ship editable English source catalogs and consume a shared message provider. Applications retain translations, ICU formatting, locale routing, recipient preferences and language/direction setup. Extraction, an ICU compiler and native catalog generation remain outside the shipped surface.
