This plugin adds a bookmarking feature to a content management system, allowing visitors to mark posts as favorites directly from the front end. It's designed for site builders and developers who want to increase user engagement by letting readers curate their own lists of saved content.

• Instant Interaction: The Interactivity API powers the favorite button, so clicks happen without a full page reload, providing immediate visual feedback.
• Persistent Storage: User favorites are saved and associated with their account or browser session, making the list available on return visits.
• Simple Integration: Install and activate the plugin to add the core functionality; it works with standard post types and common themes.
• Developer-Friendly: Built on modern WordPress standards, the code is open for extension and customization to fit specific site needs.
