Convert all PDF generation endpoints from synchronous to async to prevent blocking FastAPI's event loop during CPU-intensive operations. Changes: - Add render_html_to_pdf_async() using ThreadPoolExecutor (2 workers) - Convert all PDF endpoints to async def - Use await render_html_to_pdf_async() instead of blocking calls - Keep render_html_to_pdf() for backward compatibility Performance impact: - Prevents event loop blocking during PDF generation - Allows other requests to be processed while PDFs are rendering - Limits concurrent PDF generation to 2 workers to control CPU usage Files updated: - kjvstudy_org/utils/pdf.py (new async implementation) - kjvstudy_org/server.py (5 PDF endpoints) - kjvstudy_org/routes/api.py (4 PDF endpoints) - kjvstudy_org/routes/resources.py (7 PDF endpoints) - kjvstudy_org/routes/stories.py (2 PDF endpoints) - kjvstudy_org/routes/study_guides.py (1 PDF endpoint) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
