Thank you for taking the time to do this, but please could you add the "scala 3 only" tag to the top of the page somehow, such as was done with http://localhost:4000/scala3/book/methods-main-methods.html.

then going forwards we can also have a page for "implicit" (scala 2 style) and then a page that abstracts over the use cases of the two. Otherwise if we do not make separate pages, then this page should also cover the scala 2 way

@alvinj @julienrf what do you think?

I add one line as the first line.

Thanks! However please be aware that we are separately working on some PR to change the contextual abstractions section quite a bit
