Is there a way to see elements and containers

For troubleshooting, it would be very helpful if I could see all the shapes and sizes of all the elements and containers in my document. Is there a way to do this?

For example, if I could add fill colours or borders to each element I could see how they fit together and nest. So far I cannot see a way to do this (showing outline for the page, one for the column, one for the paragraph, one for the bullet list, one for the bullet item, etc.).

I don’t mean I expect a single parameter that I can use to make everything show an outline. But as far as I can tell there’s no way to set a fill colour or border for a column, for example? I might be missing something.

I’m imagining something like:

(specifically it would be helpful for understanding what’s going on with positioning, place, invisible blocks and suchlike in Can Typst detect the current column? - #7 by Hurtleberry but it seems generally useful)
