The book Aigner, Ziegler: Proofs from the book is generally hailed for it's beautiful Latex layout. An example chapter can be see here. The book uses side notes, so it seems to be inspired by https://ctan.org/pkg/tufte-latex.
But the choice of fonts and several details are different. Is there a package/template available, which generates a layout equal or similar to Aigner/Ziegler? Or how could one achieve a similar layout?
