This Geometry Nodes setup demonstrates how to procedurally generate rim and sphere decorations on any mesh by utilizing edge angle detection. It is designed primarily as an educational resource to help users understand practical Geometry Nodes workflows.

The node trees are kept clean and are heavily annotated with detailed text descriptions. To prioritize readability and learning, the setup avoids collapsing the logic into node groups with exposed properties, instead presenting the core concepts built entirely from base nodes. The included file is optimized for EEVEE rendering.
