📝 Blog Management System

A full-stack web application built using Node.js, Express.js, SQLite3, and vanilla HTML/CSS/JavaScript that allows users to register, log in, write blogs, and comment on posts. The system supports role-based access (authors vs. readers), blog/comment CRUD operations, and dynamic sorting of blog posts.
