28 hours	Add slider-wipe compare view	Danilo M.	1	-3/+3
	Before and after share one transform; before is drawn into after's rectangle so it is never copied at 4x size. Drag the divider to wipe, drag elsewhere to pan, wheel zooms around the cursor, double-click fits. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
28 hours	Add implementation plan	Danilo M.	1	-0/+793
	Four tasks: tested helpers, compare view, main window, end-to-end run and docs. Feeds sd-cli an EXIF-oriented PNG so rotated photos stay upright. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
