//! Phase 3 setup: state snapshot round-trip across both persistent
//! storage backends. The Fase 3 browser-session engine will write
//! `{cookies, localStorage, ...}` as opaque JSON; here we check the
//! storage layer round-trips correctly, reject path-traversal attempts,
//! and survive an "unknown session_id" lookup.
