alibaba/weex ? reverse-engineered prompt

Build me a simple Weex based demo app that shows how to make one codebase work on Android and iOS, with a clean home screen, a list of items, and a detail view when you tap one. I want it to feel like a real starter project, so include a basic layout, a little styling, and a couple of reusable components.

Please make sure it runs in the existing playground style setup, and leave clear steps for building and launching it on both platforms. If you need current setup details, look up the latest docs online and follow the project’s existing build approach. Keep it simple and practical, but make it polished enough that I could use it as the base for a real mobile app.
