Composable Svelte Internationalization (i18n)

Complete i18n solution integrated with the Composable Architecture. Handles translations, formatting (dates, numbers, currency), locale detection, and works seamlessly with SSR/SSG.

CRITICAL RULES

Rule 1: i18n State Lives in Store

Principle: i18n state is part of your application state, integrated via the i18n reducer.

✅ CORRECT - i18n in Store State

import { createInitialI18nState, i18nReducer } from '@composable-svelte/core/i18n';
