Hi Bernat,
Thanks for noticing!
In terms of writing style, my own tendency is towards longer and more complex sentences, and I have trained myself over the years to write more directly. Ven Brahmali is also an excellent, clear and direct stylist.
I did some research on style and readability before undertaking my nikaya translation. I wrote some guidelines here:

Lol, Hemingway would have loathed apps!
We used LaTeX for layout in Authenticity, and took full advantage of its excellent support for bibliographies and structured content. This is really where it shines.
All my books, in fact, use LaTeX, and yes, I use LuaTeX for its Unicode support. ( I even do freelance book layout for Dhamma books by others, as it hurts me so much to see the Dhamma disrespected by lesser typography!)
I don’t think we used a specific academic style guide, or we might have, I can’t remember.
