I can do that directly in System Settings by toggling the Obscuro option, but this is a local system setting change (it will change the global macOS appearance).

Done — dark mode is now active in macOS System Settings.

The Obscuro button is marked as selected in the Appearance panel, indicating the global appearance has been switched.
