Research direction

Start by reproducing the image-editing flow in the viewer: open an image in the web UI, edit and save it, close it, then reopen it. Trace the viewer's preview refresh and image-editing entry points to determine why the updated file is not reflected, and verify that reopening shows the saved changes.
