The #adopted-style-sheet messages can't be touched, modified, or used in any way

I just want ability to toggle visibility of #adopted-style-sheet displaying in the DevTools Elements tab so the top of my page isn't filled with 20 lines of code that has nothing to do with my work

Research direction
Investigate the DevTools Elements panel implementation in the brave browser repository, likely in the DevTools frontend code. Locate where #adopted style sheet CSS messages are rendered (possibly in a stylesheet or JavaScript file). Implement a toggle control (e.g., a checkbox or icon button) to show or hide these messages. Refer to existing similar toggles in the DevTools UI for pattern. Tests may be needed for the new toggle functionality.
