mrmr-711/suntrack ? reverse-engineered prompt

Build me a simple sunrise tracker app called SunTrack that helps people figure out the best time to wake up and leave for a morning walk or run before it gets hot.

I want it to let the user search for a city or use GPS to detect their location, then show the sunrise time for that place and automatically calculate a wake up time and a time to leave home. The app should show the schedule clearly in a clean reverse timeline, like wake up, leave home, sunrise. Use a friendly sunrise themed design and make it feel like a modern mobile app that can work as a PWA.

Please use plain HTML, CSS, and JavaScript for the main app, and if needed, make it ready to run inside an Android WebView wrapper too. It should get location and sunrise data from public APIs, and look up current docs online if you need to. Keep it polished, easy to understand, and focused on making morning planning effortless.
