// redemption operation (https://github.com/wicg/trust-token-api): it attaches a
// single signed, unblinded token to an outgoing request, hands it to the
// token's issuer, and expects a redemption record (RR) in response. The normal
// case involves a total of two network requests: one to get an up-to-date view
// of a key set the issuer provides for verifying that it's safe to perform the
// redemption, and another to send the token to the issuer.
