Build me a web app called Aerometer that shows a real time airfare price index for India.

I want a clean dashboard where users can compare domestic routes like DEL to BOM and DEL to BLR across airlines and travel sites, see fare movement by route and booking window, and view simple panels for price trends, booking pressure, route temperature, and a normalized fare ledger. It should also have a small first step CAPTCHA before fare data can be viewed, and if no live approved feed is connected, the app should clearly say the quotes are just illustrative.

Please make the frontend in Next.js with a polished but lightweight landing page and a nice visual style, and add a FastAPI backend that can serve quote data, source status, index metadata, health checks, and the CAPTCHA challenge and verify flow. Keep the data model focused on origin, destination, travel date, advance booking days, carrier, fare class, base fare, taxes, total fare, timestamp, availability, and quality flags. If you need to look up current docs online, go ahead.
