VisualCircuit Improving Functionality and Block Library

VisualCircuit currently relies on hard-coded monolithic JSON blocks, making it difficult for the community to share and extend custom logic. This project solves that bottleneck by building a curated, reusable block marketplace hosted on GitHub Pages with automated CI validation workflows. Deliverables include the standalone marketplace site, a slim frontend integration layer for VisualCircuit, automated documentation publishing via GitHub Actions, and two end-to-end robotics applications demonstrating the complete workflow.
