# Render the XPath coverage markdown report to PDF using pandoc + weasyprint.
#
# Prepends an HTML cover page and replaces the emoji status markers with
# CSS-styled spans, then hands the result to pandoc.  Runs inside the
# infix-test container, where pandoc, weasyprint and the fonts live.
#
# Usage:
#   render_coverage_pdf.sh <report.md> <report.css> <logo.png> <version> <output.pdf>
