Image library: - "Clean up duplicates" finds byte-identical images by md5, keeps one file per group (preferring the most-used, then the oldest), merges the tags/descriptions and captions of the copies, repoints slides in open decks and in .md presentations on disk, and deletes the copies after a confirmation that lists every group. - A header toggle filters to images without tags/description, so it is easy to see which ones still need attention. - The delete warning now also lists presentations on disk that still reference the image (marked "not open"), next to the open decks. Editor and accessibility (already in tree): - Interface text scaling up to 200%, keyboard-operable panel divider, keyboard-first add-slide dialog, and screen-reader improvements. - Paste a spreadsheet/CSV/markdown selection into a table cell to fill the whole grid.
