 ## Best Practices
 
 1. **Always provide English**: The `en.json` file is required as the fallback
-2. **Use fallback values**: Always provide a fallback with `|| "default"`
-3. **Organize with nesting**: Group related translations (widget, panel, messages)
-4. **Keep keys consistent**: Use the same structure across all language files
-5. **Use interpolations**: For dynamic content like names, numbers, dates
-6. **Handle plurals properly**: Use `trp()` and `_plural` suffix keys
-7. **Test all languages**: Verify translations display correctly
-8. **Consider text length**: Some languages have longer text than English
