//! Date/time conversions across the persistence boundary.
//!
//! Domain models use `jiff` (`Timestamp`, `civil::Date`); the SeaORM
//! entity models use the `time` crate (`OffsetDateTime`, `Date`) because
//! SeaORM 1.1 has no native `jiff` support. These helpers translate
//! between the two representations when reading/writing rows.
