user-synax/rarium ? reverse-engineered prompt

Build me a web game called Rarium where players collect items, show off their collection to friends, and jump into weekly quests and fights to win extra rewards.

I want it to feel fun and polished, with a clear home screen, a collection page, a place to view rewards, and sections for quests and fights. Make the item collection easy to browse, with cards, progress, and a way to see what has been unlocked and what is still missing. Add a showcase area so a player can present their best items in a nice looking profile. The weekly quests and fights should feel like the main things to do, with simple status, progress, and reward summaries.

Use a modern, game like UI that works well on desktop and mobile, and make the whole thing feel smooth and responsive. If you need to check current Next.js docs or best practices, look them up online.
