## Important Notes

### No Database Changes Required

- Language configuration is entirely file-based
- No database or OpenSearch index updates needed
- Settings are loaded at application startup and cached

### Fallback Mechanism

If a translation is missing in `fess_label_[locale].properties`, Fess automatically falls back to the base `fess_label.properties` (English).

### Language Code Format

- **Utility Classes** - All core functionality exposed through static utility methods for easy access

### Performance Optimizations
- **Caching** - Bean descriptors and reflection metadata are cached for improved performance
- **Lazy initialization** - Resources and expensive operations are initialized only when needed
