Tencent/wepy ? reverse-engineered prompt

Build me a small WeChat mini program project that uses a Vue like component style and supports reusable components, data binding, and easy page development.

I want the app to include a simple home page with a counter, an input field, and a couple of custom components so I can see how component based mini program development works. It should also support importing packages, writing modern JavaScript, and compiling styles like Less or Sass. If it helps, set up the project so I can run a build command in watch mode and then open it in WeChat Developer Tools.

Please make the starter code feel clean and beginner friendly, with a working demo and sensible defaults. If you need to check the latest setup details online, go ahead and do that.
