- Update history store to support up to 300 undo/redo states, improving user experience during complex editing sessions.
- Refactor batch handling in various components to ensure accurate history tracking and prevent unnecessary entries.
- Implement checks to avoid adding duplicate states to the undo stack, optimizing performance and memory usage.
- Enhance event handling in canvas and keyboard shortcuts to maintain consistent history state during user interactions.
- Increase undo history to 300 states, deduplicate identical snapshots
- endBatch accepts optional currentDoc to skip no-op batches
- Add AI streaming guards: disable canvas interaction during generation
- Defer transform batch close via rAF so object:modified fires before endBatch
- Restrict layout reorder to move drags only (not scale/rotate handles)
- Extend checkDragReparent to work for any parent container, not just root frames
- Wrap design apply/modify in history batches for proper undo support
- Add variable management capabilities to the document store, including setting, removing, and renaming variables.
- Implement a VariablesPanel in the editor layout for user interaction with variables.
- Enhance UI components (e.g., AppearanceSection, FillSection, LayoutSection, StrokeSection) to support variable binding for opacity, fill color, gap, and padding.
- Update code generation services to output CSS variables and React code with variable references.
- Introduce keyboard shortcuts for toggling the variables panel and improve overall user experience.
- Add support for 'thinking' state in chat message streaming to indicate processing.
- Update toolbar to parse SVG files into editable nodes, allowing for better integration of SVG graphics.
- Refactor image handling to accommodate both SVG and raster images, ensuring proper placement and scaling on the canvas.
- Improve error handling and user feedback during file uploads.
Implement code generators that convert PenNode trees to React+Tailwind
and HTML+CSS output. Add code panel with tab switching, syntax
highlighting, and copy-to-clipboard. Supports generating code for
selected elements or the entire document.
Implement history store with undo/redo stacks using structuredClone
snapshots. Add keyboard shortcuts for common operations (copy, paste,
delete, group, save, export). Implement save-as dialog (.pen file
download) and export dialog (PNG/SVG with scale options).

Set up the Fabric.js v7 canvas integration with bidirectional sync
to a Zustand document store. Includes drawing tools (select, rectangle,
ellipse, line, text, frame, hand), viewport pan/zoom, smart guides,
dimension labels, and the main editor layout with toolbar and status bar.
