Anuj579/birthday-site ? reverse-engineered prompt

Build me a beautiful birthday surprise website for someone special.

I want it to feel heartfelt and emotional, like a small gift made with code when I can’t be there in person. It should have a loading screen, a live countdown to the birthday, and then switch into a happy birthday message screen with cute icons, soft colors, and smooth animations. Make the whole experience feel warm, romantic, and celebratory, with little touches that make it feel personal and magical.

Please make it work nicely on mobile too, and keep the design clean and polished. I’d like the text and target date to be easy to change so I can reuse it for different people later. If you need to look up anything current while building it, go ahead and check the latest docs online.
