It uses the browser preference for light/dark theme by default
This doesn’t work for me. It seems like you are using leptos_use::use_preferred_dark with server-side rendering which unfortunately uses the experimental Sec-CH-Prefers-Color-Scheme header which isn’t supported by all browsers, e.g. Firefox.
In my opinion, it is way better to implement theme switching on the client side. The prefers-color-scheme media query is better supported across browsers and allows reacting to a change of the user’s system preferences.
Sounds like you are familiar with this topic. I dont have time to work more on this particular aspect (there are lots of other tasks like comment support, federation with Lemmy, etc). But contributions are definitely welcome, preferably directly to leptos_use so that others can benefit and its easier to maintain.
