I Built a Browser-Based 3D Print Overhang Analyzer — No Backend, No Uploads

The response was great, but there was a recurring question: "Can I try it without installing anything?" So I built a browser-based version . Drop an STL file into the viewport and see the overhang analysis immediately — color-coded, interactive, and fully client-side.
