Replaced inline styles with CSS classes in UI methods
Ensured all panel features and interactions work as before
Improved code maintainability and consistency with project structure
Moved all blend mode menu styles from CanvasLayers.ts to a dedicated CSS file. Replaced inline styles with CSS classes and preserved all functionality.
I updated src/css/custom_shape_menu.css with new styles for a modern look and feel, and I refactored src/CustomShapeMenu.ts to use a new HTML structure for the checkboxes that works with the updated CSS. The menu should now be fully functional with the new design.
moved all CSS from src/CustomShapeMenu.ts to a new file src/css/custom_shape_menu.css and updated the TypeScript file to use the external stylesheet. This improves code organization and maintainability.
