React-Konva Migration:
- Create KonvaComponents.tsx with declarative components
- Convert Grid, Origin, Hoop, Stitches, PatternBounds, and CurrentPosition to React components
- Add React.memo and useMemo for performance optimization
- Remove imperative layer manipulation (destroyChildren, add, batchDraw)
- Remove backgroundLayerRef and patternLayerRef
- Let React handle component lifecycle and updates
- Improve performance through React's diffing algorithm
Pattern Offset Persistence:
- Add patternOffset field to CachedPattern interface
- Update PatternCacheService.savePattern to accept and store offset
- Modify useBrotherMachine to save offset when uploading pattern
- Update resumedPattern state to include offset information
- Restore cached pattern offset in App.tsx on resume
- Add initialPatternOffset prop to PatternCanvas component
- Pattern position now persists across page reloads and reconnections
Benefits:
- More maintainable and React-idiomatic code
- Better performance with large patterns
- Automatic cleanup and no memory leaks
- Pattern positioning workflow preserved across sessions
- Improved developer experience
