//! E0432 regression: nested `src/<dir>/*.rs` + auto-generated `use super::...` imports.
//!
//! `rust_use_path_from_module_to_type` already emits the correct number of `super::` segments for
//! Rust's module tree. Prepending filesystem nesting (`src/foo/bar.rs` → depth 1) produced
//! `use super::super::sibling::Type` and broke sibling imports under `rendering/`, etc.
