# System deps
#   build-essential — compile any wheels without prebuilt manylinux artifacts.
#   The rest are weasyprint's runtime native libs (Pango/HarfBuzz/Fontconfig/
#   Cairo/gdk-pixbuf) per its official Debian install list; without them the
#   lazy `from weasyprint import HTML` in reporter.py fails and PDF rendering
#   silently downgrades to HTML-only. fonts-dejavu-core gives non-blank PDFs.
