网格灯箱图片显示顺序错误

当您使用网格并点击第一个项目，然后使用方向键在它们之间切换时，系统并非按照您上传的顺序进行切换，而是以不同的顺序进行。请在下方尝试：

切换顺序为：1、3、2、4

FIX: Preserve original image order in grid lightbox (#39968)

Inside a `[grid]` block, the lightbox arrow navigation followed column-balanced …DOM order instead of the original markdown order. For four images this resulted in 1, 3, 2, 4 because `Columns` distributes items by height into the shortest column. `lightbox.js` collects items via `querySelectorAll(".lightbox")`, which returns nodes in document order — the same scrambled order the layout algorithm produced. `Columns` now tags each item with `data-lightbox-position` carrying its original index before reordering. A new `sortLightboxItems` helper in `lightbox.js` reorders items within each grid by that attribute before they reach PhotoSwipe. The existing RTL reverse continues to apply on top, so right-to-left navigation now mirrors logical order rather than the scrambled layout. https://meta.discourse.org/t/402817
