Editioned: COA Certificates

Editioned turns any product into a numbered limited edition with a certificate of authenticity (COA) per buyer. Theme blocks show edition badges, scarcity bars, and "X of Y remaining" counters on product pages. The hosted provenance certificate shows origin, studio, materials, and a QR code buyers scan to verify. No crypto wallets, no NFTs. Auto-assigns numbered editions on purchase, revokes on refund. Exports EU Digital Product Passport data per item.
