/**
 * Axis plugin that owns a per-axis runtime list of {@link CrossLine} instances along with the
 * scene-graph groups they render into.
 *
 * Ownership model (post-refactor — the axis itself has no cross-line awareness):
 * - The plugin creates its own per-axis `rangeGroup` / `lineGroup` / `labelGroup` and attaches
 *   them to the chart-level scene-graph zones owned by {@link AxisManager}. Those zones already
 *   sit at the correct z-indices for cross-line rendering.
 * - Per-instance `CrossLine` runtime is constructed by reading `ctx.crossLine`, a factory
 *   installed via `DynamicContext.factory()` by `CrossLinesModule.register`. Community installs
 *   the cartesian implementation; the enterprise `CrossLinesModule` overrides with a polar-aware
 *   factory that branches on `axisCtx.axisType`.
 * - Lifecycle is driven by the generic {@link AxisPluginModuleInstance} hooks
 *   ({@link update}, {@link layout}, {@link onScaleChange}, {@link onGridChange}). The axis
 *   invokes them generically without knowing what cross-lines are.
 *
 * `applyOptions` is called every `Chart.applyAxes` cycle (whether or not the cross-lines options
 * changed), so the body short-circuits when the new options are structurally equivalent to the
 * previous call — preserving the pre-refactor `jsonDiff`-gated setter behaviour and avoiding
 * scene-graph detach/recreate churn on no-op updates. Per invariant I1 the options array is
 * read-only — the plugin stores its own runtime state on the per-instance `CrossLine`s.
