Site-Specific Dark Mode

By going to the url brave://flags/#enable-force-dark in Brave, you can enable browser-wide dark mode for every website you visit. This is a fantastic feature, even though there are probably 20% or more sites that have issues with this feature that makes the text unreadable unless the whole page is highlighted with CTRL+A.

To fix this issue, I propose a site-specific dark mode implementation. Just like the Brave Shield is site specific, this (I assume) would be a very easy implementation and would be greatly appreciated for both desktop and mobile.
