A JWKS document as published by an arbitrary third-party OIDC provider,
consumed (not created) by frodo — deliberately looser than
JwksInterface/JwkInterface, which model keys frodo itself
creates and can guarantee the shape of (e.g. always carrying alg).
A real external IDP's JWKS entries commonly omit fields like alg
while still being perfectly valid, verifiable keys.
