Aryan-Dhole/memorylane-v1.2 ? reverse-engineered prompt

Build me a polished photo album web app called MemoryLane for Indian families and event albums.

People should be able to sign in, upload a big batch of photos, and then the app should automatically pick the best ones, group them into meaningful moments, and write nice captions for each photo. I want a beautiful gallery experience where the finished album can be shared with a private link, and guests can react or add uploads if the owner allows it.

It should also support paid orders for premium albums and print delivery, with a smooth flow from upload to processing to finished gallery. Please make it feel modern, emotional, and easy to use on mobile and desktop. Use the repo structure that is already here, and if you need current setup details for any service, look them up online.
