//! Account-partitioned, serializable state for AWS Cost Explorer (`ce`).
//!
//! Every stored Cost Explorer resource is kept as an already-output-valid JSON
//! object (`serde_json::Value`) keyed by its ARN, name, or id. Storing the wire
//! shape directly keeps nested configuration (cost-category rules, monitor
//! specifications, subscription expressions) round-tripping verbatim and
//! guarantees the `Get`/`Describe` responses echo exactly what was persisted.
