   * SvGridChart - renders a `ChartSpec` as inline SVG. Supports grouped +

   * unified crosshair tooltip (hover a category -> all series at once),
   * focus tooltips, a clickable legend that toggles series, optional data
   * labels, and an `onSelect` drill hook. No external charting dependency.
