Copy the authoring prompt and describe your project to any LLM at the
bottom of it.
The response is a set of files, each in its own code block: project.ypf, form.json,
process.js, overlay.canvas, and whatever else the project needs.
Create a new project in the app, then paste each file's
content into the matching file with the Project Editor and
Script Editor, which edits any plain-text file. Add any new file with
Add Asset.
Save the project from the main menu, then open the Input Form and try
it. To iterate, paste the output back to the LLM along with what to change.
