//! Nested-iframe traversal + predicate finder integration tests.
//!
//! Gated behind the `integration-tests` feature; CI exercises these on the
//! integration job where a real Chrome binary is available.
//!
//! The fixture/server pattern mirrors `integration_phase4.rs` exactly:
//! wiremock serves HTML at `/`, and additional paths are mounted inline when
//! a test needs multiple routes.
