as far as I know, this isn't REALLY something that congo/hugo controls...

The colors in the generated diagram are selected by mermaid at generation time.... it's possible that a solution would be to generate the diagram twice at site rendering time, with both polarities, and use the resulting image as css... but that feels.... like the wrong way forward?

color polarity is controlled entirely clientside.... so solutions have to be clientside based.. might wanna look at the mermaid.js site n see how they're solving it elsewhere.... may provide some ideas on a way forward.

but that feels.... like the wrong way forward?

Maybe not? 👀

This exact approach is implemented for the Site Logo partial. https://github.com/jpanther/congo/blob/89ae9809559cb6807b20749df32b16b01545caa8/layouts/partials/logo.html#L7-L22

This is indeed an upstream issue and I'm not sure that forcing a page reload whenever the user changes dark mode is an ideal workaround. It seems to be a highly requested feature in Mermaid but is still yet to be implemented.
