Build me a fun browser based SQL learning game where the player is a Graduate Analyst at a fictional Singapore bank called Lion City Bank.

I want people to solve 50 plus SQL challenges that start easy with SELECT, WHERE, ORDER BY, and LIMIT, then move into joins, grouping, subqueries, CTEs, and window functions. Each level should feel like a real analyst task, like finding branches in a region, checking low credit score customers, or ranking vessels by revenue. The whole thing should run in the browser with no signup and no backend, using a small sample database that the player can query directly.

Make it feel polished and game like, with a clear level flow, challenge instructions, a SQL editor, a way to run the query and see results, and progress through difficulty tiers. Use current docs online if you need to. Build it as a modern Next.js app with TypeScript, and make sure it works well locally and for deployment.
