//! Trybuild compile-fail snapshot suite.
//!
//! Most cases have toolchain-agnostic `.stderr` files and live at the top
//! level of `tests/compile-fail/`. A handful of cases produce a different
//! diagnostic span shape between stable and nightly rustc — those have their
//! own copies in `tests/compile-fail/{stable,nightly}/` with their respective
//! expected output. The `#[rustversion::*]` helpers pick the right subset
//! at compile time, so each channel's CI job runs exactly its variants.
