% Extended list nesting to 9 levels
\setlistdepth{9}
\setlist[description,1]{leftmargin=\parindent,labelindent=\parindent}
% ... configured for all 9 levels
```
### **Font Configuration**
```latex
\setmainfont{Times New Roman}[Ligatures=TeX]
\setsansfont{Helvetica Neue}[Scale=0.9,Ligatures=TeX]
\setmonofont{Menlo}[Scale=0.85]
```
## Documentation Statistics
