Project Notes

This folder keeps implementation notes, review passes, and fixtures out of the repository root while preserving the context that led to the current demo.

Archived root-level prompts now live in ../prompts/.

Final submission status, June 15, 2026: Snap2Sim is public under build-small-hackathon/Snap2Sim, the app host is https://build-small-hackathon-snap2sim.hf.space, and the README links the demo video plus X post.
