LEKKALAGANESH/travel-unbounded-app ? reverse-engineered prompt

Build me a polished travel agency website for Travel Unbounded with a strong home page, an about page, and a contact page where people can send booking enquiries.

I want the enquiry form to feel real, not fake. It should validate inputs on the page and again on the server, show clear loading, success, and error states, and save each enquiry to MongoDB Atlas through a serverless API. If someone opens the enquiry endpoint in a browser, it should show a simple readable dashboard, and if it is called normally, it should return JSON. Make the site responsive and clean on mobile, tablet, and desktop, with attractive destination sections for India and international trips, a nice hero area, and a trustworthy professional feel throughout.

Use the project structure that is already here, keep it simple and well organized, and look up current docs online if you need to.
