This is a battle-tested Pandoc workflow that turns markdown into professional PDFs through XeLaTeX. It includes a universal build script that auto-detects your files, a production-tuned LaTeX preamble for proper table spacing, and opinionated defaults like landscape orientation for technical docs. The standout detail is how strict it is about ASCII diagrams: it mandates using the graph-easy skill instead of manual ASCII art to avoid alignment disasters in PDFs. There's also a Lua filter to strip out HTML details blocks, which is clever for keeping diagram source code in your markdown without cluttering the printed output. The verification checklist and printing workflow show this was written by someone who's debugged plenty of broken PDFs at 11pm before a deadline.
