Start by reproducing markitdown demo.pdf and trace the import path through markitdown.__main__, markitdown._markitdown, pptx, and PIL. Inspect the project's dependency declarations and verify the installed packages are compatible; done means PDF conversion starts without the reported _imaging import error.
