A Two-Sided Marketplace from a Prompt

Build a marketplace for independent ceramics makers. Sellers manage their own products and orders; buyers browse across sellers; administrators review listings and track payment and fulfilment states separately.

Include these capabilities:
- Vendor and buyer roles with separate dashboards
- Listings with images, categories, search and filters
- Cart, orders and a Stripe-ready checkout surface
- PostgreSQL-backed catalog, users and transactions
- Deployable web app with 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:
Create products under two sellers and place a test order. Verify seller isolation, order allocation and payment-failure handling before enabling live payments.
