1//! Typed storage errors (`thiserror` per crate, per the framework convention).
2//!
3//! Public APIs return `doido_core::Result<T>` (anyhow) like the rest of the
4//! framework; [`StorageError`] gives callers a matchable error type and converts
5//! into `anyhow::Error` automatically via the `?` operator.
