The convertPage method now delegates the conversion task to the new service. + +### **Benefits:** +- Code Cleanup: The `pages.js` file sheds approximately 80 lines of conversion logic that are unrelated to data persistence (Model responsibility). +- Import Performance: Since `pages.js` is a frequently loaded model, removing heavy dependencies like `cheerio` and `turndown` makes its initial load time lighter and more efficient. +- Maintainability: Future changes to how Markdown/HTML is generated/converted will only require modifying `page-converter.js`, isolating the logic from the core database model. + + +## **File Changes** +1.
