alperuyank/egg-timer — reverse-engineered prompt

Build me a small, polished egg timer that runs in the browser as a single page. I want it to feel simple and friendly, with a clean layout, nice styling, and a little personality using egg images and a sound when the timer finishes. It should let someone quickly choose how they want their egg cooked, like soft, medium, or hard, and then start a countdown right away. Please include the basics people expect, like start, pause, reset, and a clear display of the time left.

When the timer ends, play a sound and make it obvious that the egg is done. If it fits naturally, add a little visual change as the timer runs so it feels alive. Keep everything lightweight and easy to open locally in a browser. Make it feel complete, not like a rough demo. If you need to, look up current browser friendly approaches online, but keep it simple and self contained.
