Complete canvas rendering infrastructure and state management: **Type System (types/)** - Layer interface with blend modes, opacity, visibility - Canvas state with zoom, pan, grid, rulers - Tool types and settings interfaces - Selection and pointer state types **State Management (store/)** - Layer store: CRUD operations, reordering, merging, flattening - Canvas store: zoom (0.1x-10x), pan, grid, rulers, coordinate conversion - Tool store: active tool, brush settings (size, opacity, hardness, flow) - Full Zustand integration with selectors **Utilities (lib/)** - Canvas utils: create, clone, resize, load images, draw grid/checkerboard - General utils: cn, clamp, lerp, distance, snap to grid, debounce, throttle - Image data handling with error safety **Components** - CanvasWrapper: Multi-layer rendering with transformations - Checkerboard transparency background - Layer compositing with blend modes and opacity - Grid overlay support - Selection visualization - Mouse wheel zoom (Ctrl+scroll) - Middle-click or Shift+click panning - LayersPanel: Interactive layer management - Visibility toggle with eye icon - Active layer selection - Opacity display - Delete with confirmation - Sorted by z-order - EditorLayout: Full editor interface - Top toolbar with zoom controls (±, fit to screen, percentage) - Canvas area with full viewport - Right sidebar for layers panel - "New Layer" button with auto-naming **Features Implemented** ✓ Multi-layer canvas with proper z-ordering ✓ Layer visibility, opacity, blend modes ✓ Zoom: 10%-1000% with Ctrl+wheel ✓ Pan: Middle-click or Shift+drag ✓ Grid overlay (toggleable) ✓ Selection rendering ✓ Background color support ✓ Create/delete/duplicate layers ✓ Layer merging and flattening **Performance** - Dev server: 451ms startup - Efficient canvas rendering with transformations - Debounced/throttled event handlers ready - Memory-safe image data operations Ready for Phase 3: History & Undo System 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
