Save the Python script to /home/daytona/workspace/biochem-notes/generate_biochem_pdf.py 2. Execute it with: python /home/daytona/workspace/biochem-notes/generate_biochem_pdf.py 3. Output PDF should be saved to /home/daytona/workspace/biochem-notes/Biochemistry_Master_Notes_NEETPG.pdf 4. Report back: whether the PDF was created successfully, how many pages it has, and the exact file path. Write clean, working ReportLab code. Use platypus (flowables) for multi-page layout. Use Table, TableStyle, Paragraph, Spacer, KeepTogether. Do NOT use matplotlib or any external image dependencies. Everything must be drawn with ReportLab primitives. If the script has errors, debug and fix them until the PDF is successfully generated.
