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.

Empieza reproduciendo el gráfico de áreas apiladas de la captura de pantalla, usando el contexto enlazado de Plotly Graph Card y la source YAML, si se proporciona. Lee primero el renderizado de áreas apiladas y el comportamiento de relleno tonexty; estará terminado cuando haya un orden de renderizado controlable que mejore los contornos de las áreas de superficie cero sin romper el apilamiento.
