This plugin offers a straightforward API for developers to programmatically change the active theme on a site based on defined rules. It is designed for developers who need to serve different visual experiences to different users or under specific circumstances without manual intervention.

• Condition-Based Switching: Define custom logic using PHP callbacks to determine when a theme should be active. Conditions can check for user roles, browser types, mobile devices, dates, or post counts.
• Simple API: The primary method is Conditional_Themes_Manager::register(), which takes a theme identifier and a callback function that returns true or false.
• Persistent Mode: An optional setting ensures the selected theme remains active for the user's session, providing a consistent experience even if the triggering condition changes during their visit.
• Flexible Integration: You implement the rules within your own custom plugin file, keeping your conditional theme logic separate and maintainable.
• Practical Use Cases: Common applications include serving a simplified theme to mobile visitors, a special admin theme for site administrators, or a seasonal theme during holidays.
