Theme to match the OS appearance

Description

Apologies in advance if this is really obvious and stupid, but is there a theme that automatically adapts to the OS appearance as it switches between light and dark modes?

My OS is set to turn on dark mode at night, and light mode in the day.

Is there a toggle or automation that can be added into the theme to switch when the OS triggers?

Hi,

apart from the menu style, which should adapt to the OS theme, I don’t know of a Mailspring theme that implements an automated dark mode switch.
