Feature summary (what you would like to be able to do and where):

Recently T26070 was closed as successful, and that ticket mentions that due to a lack of active maintainers WMF has no plans to add dark mode on Timeless due to its lack of maintenance. I would like to experience the same white on black color scheme on Timeless.

Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):

The use cases are practically the same for dark mode on Vector 2022/Minerva.

Benefits (why should this be implemented?):

Much of the benefits are practically the same for dark mode on Vector 2022/Minerva.

The problem is that since Timeless has no active maintainers (@Isarra, the developer of Timeless, was not here for more than a while) the future of Timeless as a whole is uncertain.
