Linh2244/weather-web ? reverse-engineered prompt

Build me a beautiful weather web app for Vietnam that feels like Apple Weather, with a glassy modern look, smooth animations, and both dark and light mode. I want users to be able to search for provinces, districts, communes, and wards in Vietnamese, or just let the site use GPS to find their current location, with a fallback to Hanoi if location is unavailable.

Show the current temperature, hourly forecast for the next 24 hours, and a 7 day forecast. Also include air quality info like AQI and pollutants, plus UV index, sunrise and sunset, and moon phase. Make it work well on mobile, and let people install it like an app.

Please use free weather and location data if possible, and make the interface feel polished, fast, and easy to read. If you need to, look up the current docs online first, then build the full experience end to end.
