an example how a book may look like
a lot of pgfornaments (without using pgfornaments thanks to Dr. Lian Tze Lim from Overleaf)
can be compiled into "periodical aureo" page size (almost canon conform) but with the switcher in main.tex file if you prefer a tablet or a screen reading.
the calligraphy used for letters can be switched off for people who are not used to read handwriting, same for audio links
(If you just want to read the book, it's best to download the PDF for offline reading, rather than waiting for it to render completely in the previewer on this page.)
