Moved embroidery format-related code from utils to new formats folder:
Structure:
- src/formats/pen/ - PEN format encoding and parsing
- encoder.ts (was utils/penEncoder.ts)
- encoder.test.ts (was utils/penEncoder.test.ts)
- parser.ts (was utils/penParser.ts)
- PEN constants moved inline to encoder.ts
- src/formats/import/ - Pattern import/conversion (currently PES)
- worker.ts (was workers/patternConverter.worker.ts)
- client.ts (was utils/patternConverterClient.ts)
- pesImporter.ts (was utils/pystitchConverter.ts)
- pyodideLoader.ts (was utils/pyodideLoader.ts)
- constants.ts (PyStitch/pyembroidery constants)
Benefits:
- Better separation of concerns
- PEN encoder is co-located with PEN parser
- Import logic is in one place and extensible for other formats
- Removed utils/embroideryConstants.ts - split into appropriate locations
- Updated all 18 import references across the codebase
All tests passing, build successful.

This commit addresses multiple critical issues in pattern rendering and coordinate handling:
1. Fixed Y-axis offset accumulation in penParser.ts
- Corrected sign extension logic for 16-bit signed coordinates
- Changed to interpret full 16-bit value as signed before shifting
- Prevents coordinate drift and offset accumulation
2. Fixed color assignment for tack stitches in patternConverter.worker.ts
- Added detection for small finishing stitches after COLOR_CHANGE commands
- Assigns tack stitches to correct (previous) color instead of new color
- Uses conservative pattern matching (< 1.0 unit, followed by JUMP)
3. Made jump stitches visible in pattern preview (KonvaComponents.tsx)
- Render jump stitches in thread color instead of gray
- Use dashed pattern [8, 4] to distinguish from regular stitches
- Set appropriate opacity (0.8 completed, 0.5 not completed)
- Fixed critical bug: include previous position in jump groups to create proper line segments
4. Updated konvaRenderers.ts for consistency
- Applied same jump stitch rendering logic
- Ensures consistent behavior across rendering methods

- Remove unused imports and variables across multiple files
- Fix TypeScript 'any' type annotations with proper types
- Fix React setState in effect warnings
- Create shared embroidery constants file (embroideryConstants.ts)
- Replace magic number 0x10 with named MOVE constant
- Map PyStitch constants to JS constants using registerJsModule
- Ensure PEN encoding constants remain separate and valid
All build and lint checks now pass successfully.

Dark Mode Implementation:
- Add Tailwind config with darkMode: 'media' for system preference detection
- Update all 9 components with 200+ dark mode variants
- Semantic color backgrounds with semi-transparent overlays in dark mode
- Proper text contrast (gray-900/gray-100) for readability
- Enhanced borders, shadows, and focus rings for dark backgrounds
Component Dark Mode Updates:
- App.tsx: Header gradient, error banners, empty states
- MachineConnection: Status badges with proper dark variants for all states
- FileUpload: Pattern info cards, thread swatches, upload progress
- PatternCanvas: Canvas background, overlays, zoom controls
- ProgressMonitor: Color blocks, progress bars, state indicators with colored icons
- NextStepGuide: All status boxes (blue/yellow/cyan/green/red)
- WorkflowStepper: Progress indicators and step states
- ConfirmDialog: Modal overlays and dialog backgrounds
- KonvaComponents: Grid lines and origin markers
Pattern Visibility Improvements:
- Pattern shows full opacity (1.0) when unlocked for easy positioning
- Pattern shows reduced opacity (0.75) for unstitched areas when locked/uploading
- Helps distinguish completed vs pending stitches during sewing
- Pattern locks during upload to prevent accidental repositioning
- Canvas dragging disabled when pattern is uploading or uploaded
Status Indicator Enhancements:
- Machine status badges: All states (idle/active/waiting/complete/error) have dark variants
- Progress monitor state icons: Colored icons (blue/yellow/green/red) in both modes
- Color blocks: Proper backgrounds and borders for completed/current/pending states
- All semantic colors maintain visibility and meaning in dark mode
Canvas Lock Behavior:
- Pattern locked during upload (uploadProgress > 0 && < 100)
- Pattern locked after upload (patternUploaded = true)
- Lock indicator shows amber background with lock icon
- Cursor changes prevent confusion about draggability
- Full opacity during positioning, transparency during progress tracking

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
