Payhip?

Build a focused replacement for Payhip for one creator selling a small digital catalog, based on this public product description: “How Payhip Works - Help Center — What we do Payhip is an e-commerce platform that enables anyone to sell their work directly to their fans and followers. We provide all the tools you need to ge” Do not copy the original brand, proprietary assets, name, logo, UI, or copy; create an original visual system.

Core workflow
- Recreate only the narrow primary workflow described above, with manage products, prices, availability, and a public storefront; provide a checkout boundary or mock payment adapter; show order state, receipt, and basic export; make taxes, refunds, and payment-provider limitations explicit.
- Keep the product name and source description in a research note in the README, and turn every uncertain behavior into an explicit assumption or user setting rather than inventing a feature.
- Use a small React/TypeScript app with a portable JSON or SQLite data model, clear loading/empty/error states, and adapters around external services. Seed realistic demo data so the complete workflow works without paid credentials.

Scope boundaries
- Out of scope for v1: payment processing without a provider; marketplace discovery; full commerce operations. Do not promise feature parity, proprietary data, or enterprise reliability.

Include a README with setup, environment variables, data model, implementation decisions, privacy behavior, testing instructions, and important limitations.
