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.

Inizia riproducendo il grafico ad aree impilate dello screenshot, usando il contesto Plotly Graph Card collegato e la source YAML, se fornita. Leggi prima il rendering delle aree impilate e il comportamento di riempimento tonexty; il lavoro è completato quando esiste un ordine di rendering controllabile che migliora i contorni delle aree con superficie nulla senza compromettere l’impilamento.
