A Guest User should be able to switch color modes on a shared page

I suggest adding an option to the shared page view so that a user can toggle between light and dark mode. The current situation is that Outline uses the system default. But that might not be always the user's preferred setting for the application or the contents he is reading.

As an outline user, I already have a color mode option in the main dropdown.
I think that a simple icon/button (something subtle, like the "show contents" toggle) would be sufficient, to switch between modes on the shared page view.
