//! Tenant (organization) scope for multi-tenant services.
//!
//! This is the transport/contract type only. How a service *resolves* a tenant context
//! (DB lookups, Redis caching, lazy provisioning) is service-specific domain logic and stays
//! in that service; it inserts the resolved [`TenantContext`] into request extensions, and
//! handlers pull it out via the extractor.
