感谢 @Shauny 的报告。这次调试和修复的过程很有趣 🤓

> 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.
