//! Integration tests that run tryscript golden tests as part of `cargo test`.
//!
//! Each tryscript `.tryscript.md` file gets its own `#[test]` function so failures
//! are reported per-file. Requires `npx` (Node.js) to be installed — tests will
//! fail if it is not available.
//!
//! All tryscript files are tested as part of the normal test suite.
//! Skipped on Windows: tryscript tests use bash and Unix paths.
