//! OPAQUE protocol configuration: cipher suite selection, size constants, and
//! key stretching.
//!
//! - [`OpaqueCipherSuite`] wraps an [`OprfCipherSuite`](crate::oprf::OprfCipherSuite)
//! with OPAQUE-specific size constants and HKDF operations.
//! - [`OpaqueConfig`] bundles a cipher suite with Argon2id parameters and a
//! protocol context string.
//! - [`NN`] is the suite-independent nonce length (always 32 bytes).
