 * Renders the HTML bar labels for a single bar series. Each datapoint produces
 * a `HorizontalBarLabel` or `VerticalBarLabel` depending on the chart's
 * categorical-axis orientation; both use the split-clip pattern to paint the
 * portion inside the bar with a contrasting color and the portion overflowing
 * to the chart edge with the neutral text color.
 *
 * Rendered as a sibling of the `<Canvas>` element (not inside `BarDisplay`)
 * because HTML children of `<canvas>` are fallback content, not visible DOM.
 * See `BarLabelLayout.tsx` for the chart-level wrapper that iterates over
 * labeled bar series and mounts this component.
