Confusing recursive definition

https://docs.passwordless.dev/guide/concepts.html#discoverable-credential

"Discoverable Credential is a passkey" but also "Passkeys are an example of Discoverable Credentials"?

Open the Discoverable Credential section at the linked concepts.html anchor and read the two quoted definitions in context. Clarify the relationship between passkeys and discoverable credentials so the definitions are no longer circular, then verify that the revised wording is consistent and understandable on the rendered documentation page.
