This diagram visualizes the architecture of a portfolio website with features for user login, theme customization, and portfolio preview. The process starts with the user logging in and selecting themes from local theme storage, which are then customized through the theme UI and processed by the YARTL engine. The system uses user data storage for login information and website data storage for the portfolio website and preview. The architecture provides an efficient design flow, from user interaction to final portfolio display. Ideal for developers designing portfolio websites or managing website hosting, it emphasizes user-friendly UI, theme management, and backend storage integration.
