slug VARCHAR(255) UNIQUE NOT NULL,
category VARCHAR(50) DEFAULT 'general',
feature VARCHAR(255) NULL,
summary TEXT NULL,
content LONGTEXT NOT NULL,
metadata JSON NULL,
status ENUM('published', 'draft', 'archived') DEFAULT 'published',
view_count INT DEFAULT 0,
last_updated_at TIMESTAMP NULL,
created_by BIGINT NULL (FOREIGN KEY to users),
updated_by BIGINT NULL (FOREIGN KEY to users),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
