Let Customers Rotate, Recolour and Configure in 3D

Build a desk configurator with selectable sizes, finishes and leg styles. Show the chosen configuration in 3D alongside its itemised price and a quote request containing the exact selection.

Include these capabilities:
- Interactive 3D viewer — rotate, zoom and inspect the product
- Real-time material, colour and option switching
- Options, variants and pricing stored in PostgreSQL
- Quote or add-to-cart flow wired to the configuration
- Live preview, one-click deploy and full code export

Build the complete working project with its routes, data model and interactions. For saved or private data, implement persistence, authentication and server-side permissions. Keep API credentials on the server. For external services, document the required setup and use test mode until real accounts are connected. Do not present a simulated integration as a completed live connection.

Make the interface responsive, with accessible labels, keyboard navigation and visible focus. Include loading, empty, validation and error states. Use clearly labelled sample data, never invented customer testimonials or results. Choose a visual direction suited to this project and keep typography, spacing and controls consistent. Explain how to run, test, export and deploy the source.

Verify this end-to-end flow:
Change each option, reload a saved configuration and request a quote. Verify the model, price and submitted specification describe the same product.
