GA/GSC dark theme (Pure CSS Injection)

My eyes hurt when checking Google Search Console and Google Analytics at night. So I created this simple utility to inject some dark theme CSS into the GA and GSC pages. Highlights: 1. It will follow your system's dark/light settings. It won't force your GA and GSC pages to become dark when you don't want it. 2. It will mark the "<html>" element as black, so even if you're opening the pages for the first time, your eyes won't be hurt by the flash of a blank white screen. 3. Everything in this extension is purely some CSS code. No JS involved. It's super safe. No extra permission needs!
