Tanjamul-Azad/Wish ? reverse-engineered prompt

Build me a simple interactive birthday page for Preyoshi that feels like a sweet little surprise, not a normal app. It should be one shareable link, work great on phones, and have nine little screens that guide her through the experience, starting with a cover, then a photo reveal, a live countdown, a memory scrapbook, a letter she has to open, a date invitation, and a final plan screen with her choices turned into something like a cute invitation.

Keep it as a static site with no framework and no extra setup. I want the words and photo references to live in one content file so I can easily swap in my own message and pictures, then run a build and get one finished HTML file to send her. Make it feel warm, paper like, and polished, with nice buttons, smooth transitions, and small touches like confetti or sound if that fits. If you need to look up current docs online, go ahead.
