 ## Recent Enhancements
 
+- Added the MIT license for br0tkasten.de, included it in the runtime image, and configured OCI manifest annotations and Buildx for Zot's required vendor and license checks.

 - `efddb34`: Hid the fullscreen navigation arrows on mobile and kept swipe navigation in chronological order.
 - `99f9f64`: Added a fullscreen download button and changed the light-mode caption color back to `#303030`.
