1//! Build a `TempProject` — a self-cleaning temporary directory pre-populated
2//! with files — and emit a `Report` describing the lifecycle.
3//!
4//! ```text
5//! cargo run --example temp_project
6//! ```
7//!
8//! The temp directory is removed when `project` is dropped. The example
9//! prints the staged paths, asserts they exist on disk, then drops the
10//! handle and confirms the cleanup.
