vipinkumar721/mern-weather-app ? reverse-engineered prompt

Build me a simple weather app in React that feels clean and easy to use.

I want a page where someone can type in a city or place, hit search, and see the current weather right away. Show the main details people care about like temperature, condition, humidity, wind, and maybe an icon or simple visual for sunny, cloudy, rain, and so on. Make it look nice on mobile and desktop, with a polished empty state and a friendly error if the place cannot be found.

Use the existing React app setup in this project, and keep the code straightforward. If you need a weather API, use one that works well for a small demo and look up the current docs online if needed. Please make it feel like a finished little app, not just a bare template.
