1//! Wire-protocol SCRAM-SHA-256 authentication errors.
2//!
3//! Supports SCRAM-SHA-256 (Postgres 10+) as the primary authentication method.
4//! The `AuthError` here is specific to the wire protocol handshake — NOT the
5//! same as `fraiseql_error::AuthError` (domain) or `fraiseql_auth::AuthError`
6//! (OIDC/JWT middleware).
