Client-side (local) exporting

  1. Press Export locally. It calls exportChartLocal() directly, the same way the reporting application does from its own menu item. A PNG must download, keeping the purple and teal series colors defined in the shadow root, and the log must show one chart-before-export / one chart-after-export.
  2. Open the chart's context menu (☰, top right) and pick Download PNG image. Same result: the download happens in the browser, with no export server involved.

Both steps fail on main: step 1 logs ERROR: Cannot read properties of undefined (reading 'apply'), and step 2 silently posts to export.highcharts.com instead of exporting in the browser — the broken wrapper also stops the module from switching the menu items to their local variants.
