Mesh Sharpen - Geometry Nodes (Blender 4.1+)

• Sharpens geometry by leveraging curvature as a weighted contribution to adjust the position of vertices on the mesh.
• Note that this process may slightly reduce the overall volume of the geometry.
• Requires sufficient geometry for curvature analysis but without being too heavy.
