- Fix canvas tainting: patch crossOrigin before loadFromJSON in all paths (init, sync, undo/redo)
- Fix clipboard copy-to-system with proper async blob handling and error toasts
- Fix zoom wheel: normalize deltaY across mice/trackpads with consistent 8% step
- Add operations module: alignment, distribution, normalization, arrangement, flip, grayscale, lock, overlay compare
- Add breakSelection() to fix ActiveSelection relative coordinate bugs
- Add shortcuts help overlay (? / F1) auto-generated from registry
- Add grid overlay toggle (G key)
- Fix 10 shortcut bugs: Ctrl+Y/P conflicts, ? key matching, arrow conflicts, Ctrl+S intercept, context menu stale objects
