Is there a way to input a script (processing layer) that runs on the LaTeX code before it is rendered to PDF?

Description

Some limitations regarding rendering from Quarto to PDF could be addressed with an intermediary processing layer.

Example of application: The inclusion of \legend after figures and tables.

I don't know what exactly you want to achieve, but Quarto converts your document to markdown / Pandoc AST which is then handled by Pandoc itself.
You could use format: latex to have the latex code, then do whatever you want to compile the document yourself.

Oh, I see... I need to take some time to study Pandoc. Thanks for the prompt response @mcanouil!

Pandoc is emebedded inside Quarto.
I don't think you need to study Pandoc (although in the long run it could be useful).
As I said, you only need to use format: latex then you'll have your latex file for you to do manual edits and then compile using whatever LaTeX engine.
