//! Persistent backends for [`DeviceStore`](super::store::DeviceStore).
//!
//! Mirrors [`session::storage`](crate::session::storage): one submodule
//! per backend, plus a shared `sql_common` for the codec + error
//! surface every SQL backend reuses.
//!
//! # Backends
//!
//! - [`SqliteDeviceStore`] (`device,sqlite`): production-grade store
//!   backed by sqlx. Optional AES-256-GCM envelope on the bindings
//!   column.
//! - [`PostgresDeviceStore`] (`device,postgres`): same shape as the
//!   SQLite backend with `$1`-style bind syntax.
//! - [`MysqlDeviceStore`] (`device,mysql`): same shape as the SQLite
//!   backend with `?`-style binds + `ON DUPLICATE KEY UPDATE` upsert.
//!   Compatible with MySQL 8.x and MariaDB 10.5+.
//! - `ValkeyDeviceStore` (`device,valkey`): Valkey-backed store with TTL eviction.
