Before	After

Pull Request Overview

This PR refactors CSS styling to extract stroke-width properties into a separate reusable CSS class (StrokeWidth2). The change enables composable styling by allowing multiple CSS classes to be combined instead of hardcoding stroke width values in individual class definitions.

Key changes:

• Introduced a new StrokeWidth2 CSS class with stroke-width: 2
• Removed inline stroke-width values from OutlineStroke and WallBase classes
• Added get_class_names function to concatenate multiple CSS class names
• Applied the new StrokeWidth2 class to outlines and walls that previously had hardcoded stroke widths
