This plugin adds a customizable alert message to the top of every article on a content management system. It is designed for site administrators who need to display notices, warnings, updates, or promotional messages directly within their published content.

• Custom Alert Message: Administrators can define the exact text that appears in the alert box, allowing for site-wide notices or post-specific updates.
• Color Selection: The alert's background color can be chosen from a set of predefined options, enabling visual categorization (e.g., info, warning, success).
• Admin Settings Panel: All configuration is managed through a dedicated settings page built using the CMS's standard Settings API, ensuring a native and secure interface.
• Object-Oriented Code: The plugin is structured using object-oriented programming principles, promoting maintainable and organized code.
• Multiple Variations: The system supports different alert styles (info, warning, error, success) to match the tone and purpose of the message being conveyed.
