Dark Mode?

[roadcall]

Can a dark style be enabled to allow users to switch between?

Something basic, but easier on the eyes.

Examples:
Themes:
- ProSilver Dark: https://www.phpbb.com/customise/db/styl ... lver_dark/
- purplexion: https://www.phpbb.com/customise/db/style/purplexion/
- An official theme uploaded to a Git repo that allows user contributions.
Extensions (not tested)
- Dark Mode: https://www.phpbb.com/customise/db/extension/darkmode/

Dark Reader works pretty well, also on 720pier.ru
