Write all 10 JS files to /home/daytona/workspace/mri-radiology-teaching/ 2. Each file should produce 18-22 well-designed slides 3. Use tables for comparison data (addTable), colored boxes for key points, varied layouts 4. For bullet lists use addText with array of bullet items 5. Execute each JS file with `node filename.js` 6. Verify each .pptx file was created 7. Report back the full list of created files with their paths Make the slides EDUCATIONAL and CONTENT-RICH. Include actual radiology facts, values, and clinical information - not placeholder text. Use the medical knowledge about MRI to fill slides with real content. When done, report: the list of all 10 .pptx file paths that were successfully created.
