PDF Production

A self-contained toolkit for generating and processing PDF documents, built entirely on open-source libraries and open-licensed fonts. It organizes work into three production lines and routes each request to the best one.

Before anything: fonts

All three lines need Chinese + English fonts. They are not bundled in this skill to keep the repository light — instead, fetch them on first use with the bundled helper:

python "<skill_dir>/scripts/ensure_fonts.py"

This downloads four families (Noto Serif SC, Noto Sans SC, Source Serif 4, Source Sans 3) in Regular + Bold weights to a local cache and prints the cache directory. Never hardcode font paths — always ask the helper for the location. See references/fonts.md for the full font policy and why these families were chosen.
