== Background
This ticket will track the release of dark mode as a beta feature on desktop across wikis.
== User story
- As a logged-in user, I want the ability to opt into dark mode as a beta feature, so that I can quickly benefit from the feature and test the new feature before wider release
== Requirements
[-] All subtasks are resolved and their code is in production
[-] Dark mode must be packaged with the current "Accessibility for reading" beta feature, which enables the appearance menu and its functionality
[-] Upon deployment, the dark mode option will be made available in the appearance menu
[-] Selecting dark mode will switch the interface to dark mode
[] The default setting for the dark mode option will be "light"
- Note: We released with a default of "automatic". After reviewing the difficulty and disturbance to change the initial default, we decided to keep the default as "automatic"
== BDD
