staringos/mtbird — reverse-engineered prompt

I want a browser based low code page builder that I can run locally and use like a drag and drop editor for building HTML pages and simple websites without writing much code. Please set up this repo so it starts cleanly on Node 18 or newer, opens on localhost, and includes a working demo where I can add components, move them around, change styles, and preview the rendered result.

It should feel like an embeddable editor and renderer, not a full back office app, since I think this repo is mainly the front end editor part. If the project already supports things like Wechat mini program output, custom extension points, and data visualization blocks, keep those available or at least wired in the way the repo intends. Please make the developer experience smooth, fix anything blocking startup, and leave a simple explanation of how to run it and where the main demo is. If you need details, check the current docs online and follow the project’s intended setup.
