1//! Schema-declared `Json` columns need a model-struct field type that's the
2//! same on every backend so the same struct compiles on server and on
3//! embedded (including `wasm32-unknown-unknown`, which can't depend on sqlx).
4//!
5//! This newtype lives in `cratestack-core` so every backend can reference it
6//! without introducing a cyclic dep. `cratestack-sqlx` provides the sqlx
7//! `Type` / `Encode` / `Decode` impls on native targets.
