Build me a small browser app called Heart that feels polished and easy to run locally. I want it to open to a simple, beautiful heart themed experience, with a clean full screen layout, smooth animation, and a romantic or warm visual style. It should feel like something someone could send to another person as a cute little web surprise, not like a boring demo.

Please use TypeScript and a simple Vite style setup so I can install it with npm install and start it with npm run dev. Keep the code clean and organized, and make sure it works on desktop and mobile. Add nice styling, gentle motion, and a little bit of interaction so the page feels alive.

If you need current docs for the tooling, look them up online. I don’t need a big backend or login system, just a finished front end app that runs smoothly.
