//! Shared storage error type.
//!
//! `StorageError` is the error returned by every `ZLayer` storage operation.
//! It was moved here verbatim from `zlayer-api::storage::deployments` so that
//! the generic adapter ([`crate::JsonStore`]) and every domain store can
//! share a single error type without depending on `zlayer-api`.
