## Catalyst Core: Multi-Language Lesson Update

The Catalyst Core course's Internationalization lesson is now called Multi-Language, with a reframed introduction and an expanded look at translating BigCommerce data.

* **Renamed lesson** — "Internationalization" is now "Multi-Language" across the course navigation and cross-references.
* **Reframed introduction** — leads with BigCommerce's support for multiple languages on a single storefront channel, with the Next.js App Router Internationalization library covered as the key piece of architecture that enables it.
* **Expanded BigCommerce Data section** — adds a bulleted rundown of translatable content types and both available methods for providing translations (GraphQL Admin API and control panel), along with a control panel screenshot.
