Thank you, this is really interesting! However, it seems to introduce a new issue. When sorting was active, the column was highlighted with a darker font, but now everything is dark, making it difficult to tell which column is being sorted. How about using opacity to improve visibility? What do you think?

It would be great to simplify our SCSS theme and rely more on Bootstrap, where we could just increase the minimum contrast variable—but that’s beyond the scope of this PR.
