select_projection_embed.rs

1//! `.select(...)` projection through embedded sub-fields. Field paths
2//! into an embed flow through the existing `Path<T, U>: IntoExpr<U>`
3//! chain, so no production code change is required for this case to
4//! work end-to-end; this file is the integration coverage.
