When is the julia setup file executed?

Description

The Julia setup file (https://github.com/quarto-dev/quarto-cli/blob/main/src/resources/jupyter/lang/julia/setup.jl) is setting theme arguments for CairoMakie -- is there a place in the documentation that outlines when this file is executed?

If not, there is a risk of the user calling CairoMakie.set_theme!() early in the script and removing some of the default options, which would create some discrepancies between the results when using quarto and the results when using update_theme!(), especially when passing screen config arguments this way.

(I agree this is a mess, and I know precisely why you're asking!)

It's an artificially-inserted first cell in the notebook. It happens in line 127 of notebook.py.

Just to keep you in the loop: we're currently having a discussion about how to expose and document this part to minimize the chance of users spending time chasing down this problem. Thanks for the patience!

More concretely in the case of julia, the code in setup.jl is interpolated with the appropriate values and then added as a code cell.

Nice - I started looking for possible issues after using set_theme! and activate! gave strange results. Now that I've seen the code, I know what to avoid when changing the themes.
