描述

Currently the lightbox displays one image at a time. If one hits an arrow key to the left or to the right, the page is transitioned to the previous or next page in the content hierarchy.

Desireably one could use the arrow keys to navigate a gallery of all images in the same lightbox, in case it's activated. Page transitions would have to be omitted during that time.

研究方向
The issue requests adding keyboard navigation (left/right arrow keys) to the lightbox gallery, so that users can browse images without triggering page transitions. First, locate the lightbox implementation in the repository (likely in assets/js/ or similar). Then, add an event listener for keydown events when the lightbox is active, and programmatically navigate to the next or previous image. Ensure that the default page navigation behavior is suppressed while the lightbox is open.
