Dark Reader inverts or restyles pages that only ship a light theme. Chrome, Firefox, Edge, and Safari all have a listing. The extension is free; a paid option exists if you want to fund it.
Some campus portals and exam software look wrong with it on. Turn it off per site rather than fighting the invert. It does not save the article. It only changes how it looks.

Leave it on globally, then whitelist the two university sites that invert badly. Pair with uBlock Origin so you are not restyling banners.
