There is no official dark mode for the wiki page. On the Wikimedia page they mention something about a browser extension.
Firefox has a dark mode but this will not work on the wiki page.
Is there a dark-mode for the wiki in the pipeline ?

The workaround so far is to copy and paste a dark-mode css from:
into:
Skin > (Fedora (default) custom.css)
There are still some pages not displayed in dark-mode, like the preferences. I also tested the custom.css for shared CSS, no change.
FYI - I use the Dark Reader extension for Firefox to handle web sites that are not dark-mode friendly. The website is Help – Dark Reader

With the extension it looks good. However a extension independent solution would be great/prefered.
I do have several systems with access to the wiki.
Going to dig a bit and look if I can find the CSS we do use. Probably there is a Podman container with it, to play around.
On the fedoraproject.org website we do have a nice solution to siwtch.
I will give feedback.
Agreed a supported dark mode is the best option.
It can be designed to look good in dark mode.
I found it:
Ryan Lerch / Forks / Fedora Mediawiki Theme · GitLab
I try to go thru, and have a look if it is possible to adapt for a dark-theme switch. The fedora container is still on F39. Maybe it is possible to fix this also 
. I check with the maintainer.

Incorporating Wikipedia’s Vector skin should provide this, if it doesn’t already come with newer versions of upstream MediaWiki: [1]
this isn’t a MediaWiki thing to implement, it’s a skin thing. Some skins do have dark mode support (Category:Skins with dark mode - MediaWiki), and there are various ways to implement it on existing setups, like Extension:DarkMode - MediaWiki. BTW, there are several efforts to make this happen: ⚓ T26070 [GOAL] Provide a dark / night mode skin or theme.
