Hello, Quarto: A World of Possibilities (for Reproducible Publishing) 

Thank you, dear Prof. Mine, it is a very informative Quarto tutorial. :)

Mine - for a book project in Quarto where do you suggest the libraries should be loaded? In each chapter separately or in some sort of front end document? As a LaTeX user I would be apt to put all my libraries (in LaTeX usepackage) in a single place. Does it matter?
