frappe/builder ? reverse-engineered prompt

Build me a Frappe based website builder that feels simple and visual, kind of like a Figma style editor for making web pages without coding.

I want users to be able to drag, edit, and preview pages in the browser, switch between desktop, tablet, and mobile views, and publish a site with one click. It should support AI generated page creation from a text prompt, dark mode, and a clean responsive design. Please also include a basic CMS so pages can pull in dynamic content from the database, plus a way to add custom scripts and bind content to data or URL parameters.

Make it fast, production ready, and easy to run locally with Docker and also with the Frappe development setup. If you need to look up the latest Frappe or Vue docs online, go ahead.
