//! Types of the OxygenHub JSON API (hub spec §12.1). Everything here is
//! `serde` data with no behaviour, so clients in other languages can be
//! generated from it and the server can never drift from them.
//!
//! Shapes reuse `oxy --json`'s where one exists (hashes as lowercase hex,
//! times as milliseconds since the epoch), so tools written against the
//! command line work against the hub.
