Build me a clean weather radar app that lets people see rain, storms, warnings, lightning, and forecasts on a map without a lot of clutter. It should open in the browser, but also work as an installable app on desktop and Android, with a simple full screen feel and good support for different screen sizes. I want the main experience to be easy for everyday users, with a search box, play and live controls for radar, a timeline for recent scans, and a layers menu to turn different weather views on and off. It should also let people tap the map for local forecast details, save a few important places, and get alerts when warnings are nearby. Please include storm replay and future radar too, but keep the extra tools tucked away so the interface stays simple. If you need to look up current docs online, go ahead.
