//! Wire types for `/api/mobile/v1`.
//!
//! Field names mirror the JSON exactly (see `GitGudWeb.Api.Mobile.JSON`
//! on the server), so a field that stops matching is obvious on both
//! sides. Everything the server can leave out is `Option` or defaulted:
//! the CLI has to keep working against a forge a few commits behind it.

// The wire shape is the point: fields the CLI doesn't render yet are
// still what the server sends, and dropping them would mean rediscovering
// them the next time a command needs one.
