Vedant-Raju-Borker-2005/Interior_Design — reverse-engineered prompt

Build me a polished InteriorAI web app for homeowners in India. I want people to sign up, choose their BHK size and budget, get suggested interior design packages, customize rooms in a live 3D view, swap furniture and finishes, and see the total price update instantly.

Add an AI visualizer that turns the selected room setup into realistic looking interior renders in styles like modern, Scandinavian, luxury, art deco, Mediterranean, and tropical. It can be a simulated AI render flow if needed, but it should feel real and fast.

Also include a professional PDF quotation with room wise items, GST, terms, and final pricing. Users should be able to match with verified contractors by pincode and track project milestones like electrical, false ceiling, woodwork, painting, and photos.

Use the existing frontend and backend setup, keep it easy to run locally, and make the UI look premium, smooth, and trustworthy. Look up current docs online if you need to.
