## Ownership model {#ownership-model}

Every application owns its `i18n.config.json` and application catalogs. Reusable packages may ship built-in catalogs, but the application chooses which ones to merge and may override their messages.

This keeps product copy under application control without duplicating translations from shared packages.

## Workflow {#workflow}

1. Configure locales and catalog sources.
2. Install the Vite plugin.
3. Load one catalog into `I18nProvider`.
4. Extract and translate application messages.
5. Use the Devtool or Message Studio during development.
6. Compile compact, cacheable production assets.

## Package entries {#package-entries}

- `@workspace/i18n` provides the React runtime.
- `@workspace/i18n/catalogs` loads generated catalogs.
- `@workspace/i18n/devtool` provides development surfaces.
- `@workspace/i18n/vite` configures Vite.
- `workspace-i18n` exposes the CLI.
