## Summary by CodeRabbit

* **Chores**
  * Removed an unused development dependency.
* Updated dotLottie/Lottie-related dependency versions across packages
and replaced a removed player dependency with the new package.

* **Refactor**
* AI animated icons now re-export from a shared component and are loaded
only in the browser, reducing upfront bundle weight and centralizing
icon assets.
