This plugin automatically adds a visible notice to individual posts that were published a specified number of years ago or earlier. It is designed for site owners and publishers who want to maintain transparency with their audience about the potential age and relevance of their older articles.

• Automatic Age Detection: The tool checks the publication date of each post and displays the message only on content that meets or exceeds your defined age threshold, which is configurable from the settings.
• Fully Customizable Message: You control the exact text, heading, and HTML structure of the notice. Separate fields allow for singular and plural message forms (e.g., 'This post is 1 year old' vs. 'This post is 2 years old').
• Custom Styling Control: A dedicated CSS field lets you style the appearance of the message box directly. You can also define a custom CSS class for the message wrapper to integrate with your site's existing theme styles.
• Granular Activation: The message remains inactive by default until you explicitly enable it in the settings, preventing unintended display on a live site during setup.
• Developer-Friendly Filters: For advanced customization, the plugin provides filters that allow developers to modify its behavior, such as changing the conditions for where the message appears beyond just single posts.
