//! GUI runtime tests (TRAFFIC-14 release gate).
//!
//! Status: ENABLED (round 3). The old "exits 101 before AppStarted" was the
//! broken Makepad pin. On Linux these need a display: run under
//! `xvfb-run -a` (CI does). They build `--release` via the harness. Meanwhile `tests/runtime_ui.rs`
//! covers the production tick/lifecycle path headless, and
//! `tests/ui_basic.rs` is labelled as smoke only.
