//! # clasp-crypto
//!
//! E2E encryption add-on for the CLASP protocol.
//!
//! ## Layers
//!
//! - **Primitives** (`primitives`): Pure crypto operations — AES-256-GCM,
//!   ECDH P-256, HKDF-SHA256, ECDSA P-256. No CLASP dependency.
//! - **Protocol** (`protocol`): E2ESession state machine for key exchange
//!   over CLASP paths.
//! - **Storage** (`storage`): KeyStore trait with MemoryKeyStore.
//! - **Client** (`client`, behind `client` feature): CryptoClient wrapper
//!   for transparent encrypt/decrypt over a `clasp_client::Clasp` instance.
