It's funny that you say that because my course websites for my students both:

1) make it difficult to select or copy text, 2) and even if you manage it, you discover that the actual text in the webpage source is encrypted,

mainly so they don't vibe-code their homework assignments. So I guess it rates high on my taste scale.

(kidding of course; but you can always bring your own stylesheet to the party)

I wonder how well this works for you, considering screenshots are a thing.
