CoreBunch/Instatic ? reverse-engineered prompt

Build me a self hosted visual CMS for making static websites, something like a simpler Webflow or Framer but with clean HTML output.

I want an editor where I can design pages on a canvas, drag in text, images, buttons, forms, and reusable components, then publish the site from the same app. It should support templates, a home page, blog posts, and reusable layouts like a header and footer. I also want a content area for pages and posts, a basic admin login with roles, media uploads, and form submissions stored in the app instead of using a third party service.

Make it feel fast and polished, and when the site is published it should output plain semantic pages with minimal CSS, not a heavy front end app. If it helps, look up current docs online for any setup details you need. Use TypeScript and keep it easy to self host with a simple local setup and a Docker option.
