x-Default Fallback Configuration: Designate a primary default fallback URL using the x-default attribute to serve unmatched international browser locales.
Routing Agnostic: Native integration fetches URLs directly from OpenCart core routing rules, ensuring full compatibility with custom SEO URL structures.
OpenCart 4 Optimized: Built specifically to leverage OpenCart 4 extension architecture and event systems.
