… series Add opt-in pointer-position-based interaction detection for line/area series behind `experimentalFeatures.enablePointerPositionBasedInteraction`. When enabled, the chart uses the pointer's position to determine which series is closest, rather than relying on SVG element hover events. For area series, it detects whether the pointer is inside the filled area. For line series, it finds the curve closest to the pointer's vertical position. The detection uses actual d3 curve evaluation (via captured bezier segments) instead of linear interpolation, so hit detection matches the rendered curve shape for all curve types (monotoneX, catmullRom, natural, etc.).

Summary
experimentalFeatures.enablePositionBasedPointerInteractionfor line/area seriesChartExperimentalFeaturesis generic overSeriesType, so the feature only appears in types for charts that include line series
