The AI proposes changes, but all file writes and commands are applied through a constrained local execution layer rather than directly by the model. The video shows a single end-to-end run from prompt to generated page, with no manual intervention during execution.
The intent of the demo is to illustrate controlled execution, not model capability or design quality.

Happy to answer technical questions about the execution layer.
