Subhranilbera/valentine_gift ? reverse-engineered prompt

Build me a cute Valentine gift webpage that feels sweet, playful, and romantic when someone opens it.

I want it to be a simple single page experience that works right in the browser, with a lovely Valentine themed design, soft colors, hearts, and a nice surprise or message for the person viewing it. Make it feel polished and charming, not generic, and make sure it looks good on both phone and desktop.

If it makes sense, add some light animations or interactive touches so it feels more special, but keep it easy to open and share as a link. Use the current docs online if you need to check anything. Please keep everything self contained and make it feel like a finished little gift instead of a rough demo.
