+The **Enterprise Internationalization Architecture** for the monorepo.
+
+Provides a Hybrid Namespace Architecture combining a centralized i18n engine with decentralized, lazy-loaded feature dictionaries. Features strict TypeScript typings (including nested keys), optional backend synchronization with automatic error rollbacks, and a deep-merge mechanism for dynamic tenant-specific vocabulary overrides.
+
+**Key Capabilities**:
+
+| Feature | Description |
+|---|---|
+| 🌐 Hybrid Namespaces | Centralized `common` corpus + lazy-loaded feature dictionaries. |
+| 🛡️ Strict Typings | Native TS autocomplete for nested paths (e.g., `header.title`) via module augmentation. |
+| 🔄 Safe Backend Sync | `changeLanguage` accepts a `syncCallback` with built-in rollback if the API fails. |
+| 🏢 Tenant Overrides | `applyTenantOverrides` performs a partial deep-merge to selectively override terminology. |
+
+**Documentation**: [README.md](packages/core-i18n/README.md)
