through WalletExtension. Each entry describes one card the user can add
to Apple Wallet from inside the Wallet app.

the issuer backend; Wallet uses it to filter out cards that are already
provisioned on the device, and it is echoed back to the issuer endpoint
when the user adds the card.
The card art must be a PNG without personally identifiable information (Apple requirement: square corners, no PII such as the full card number).
