Theme switching (light/dark)

On a related note, how hard would it be to implement a theme-switching button for this template (aka light/dark mode)?

I looked into how hard it would be to do myself and stumbled upon this: https://yonkov.github.io/post/add-dark-mode-toggle-to-hugo/

I haven't looked too closely on it. But it would be fantastic to be able to just set dark and light palette, and then get a switch for it.

On my site, I ended up implementing it as in #50 (comment) but even simpler, still using the media query (without any button):

BachoSeven/bachoseven.github.io@aa597a2#diff-96dd75a968976edd5e03170268ed9085733f75c3fb24f992ae613c89e6de42dc

This uses an additional paletteLight variable in [params.theme] for configuration.
