//! Cross-platform integration tests for xa11y.
//!
//! These tests require a running test application (xa11y-test-app) with an
//! accessibility provider. On Linux, this means Xvfb + D-Bus + AT-SPI2.
//!
//! Run with: ./run_integ_tests.sh  (Linux)
//!           ./run_integ_tests_macos.sh  (macOS, when provider is implemented)
//!
//! All tests are `#[ignore]` — the harness script runs them with `--ignored`.
