   Image Rename Tool — gallery.css
   Step 2: toolbar (sort / remove) + draggable card list, each
   showing old→new name live preview, checkbox, drag handle.
   A LIST layout (not a grid) is used here on purpose — filenames
   need horizontal room to show "old → new" side by side, which
   a square thumbnail grid (like the format-converter tool) can't
   give without truncating both names into unreadable slivers.
