**Title:** Implement real-time Markdown to Word conversion with advanced formatting and auto-captioning
- Added `app.py` with Flask backend for real-time Markdown to Word conversion using python-docx - Implemented `convert_md_to_docx` function with support for headings, tables, code blocks, images, and blockquote styling - Created `templates/index.html` with responsive UI featuring dual-panel editor/preview layout - Added `static/script.js` for client-side functionality including live preview, toolbar buttons, and export workflow - Enhanced `static/style.css` with modern styling for editor, preview, and settings panels - Updated `README.md` to document features, usage, and customization options - Added `requirements.txt` with dependencies: Flask, python-docx, markdown - Implemented auto-captioning for images and tables with sequential numbering - Added table pagination support with header repetition across page breaks - Integrated configuration settings panel for customizing styles, captions, and document options
