enable control of rendering order in stacked area charts (line colors)

I am plotting a stacked area chart showing (positive y side) power consumption "from grid" (red) and "from solar" (orange) - in this order. Note that on the left-hand side of the chart, (non-zero red and zero orange), the red area is has an orange outline. While it is reasonable, taking into account that red area is rendered before orange, it is not visually appealing and can be confusing to the user.

A preferred solution would be to somehow render the chart top-down (I do realize that both the stacking mechanism and tonexty fill currently depend on a bottom-up rendering order). In the example above, that would allow red outlines to be rendered last, covering zero areas above them.

I am using Plotly Graph Card for Home Assistant, so I do not have a JS code to include. I can provide source YAML code if that helps.

まず、スクリーンショットの積み上げ面グラフを再現し、リンクされている Plotly Graph Card のコンテキストと、提供されている場合は source YAML を使用します。最初に積み上げ面のレンダリングと tonexty の塗りつぶし動作を確認してください。完了条件は、積み上げを壊すことなく面積ゼロの輪郭を改善できる、制御可能なレンダリング順序です。
