//! Integration guard for the `aura chart` viewer's x-mode (ordinal default + continuous
//! toggle), panel cursor-sync, and interaction-plugin wiring. These live in
//! `chart-viewer.js` and cannot be checked from Rust; this shells out to `node`, running
//! `tests/chart_viewer_xmode.mjs`, which drives the pure `buildCharts`. `node` is
//! REQUIRED: if absent this test FAILS.
