This plugin modifies the standard post editor interface to enforce single-category assignment for content. It is designed for site administrators and editors who need to maintain a strict, organized content taxonomy where posts belong to one primary category only.

Single Selection Enforcement: Changes the default multiple-choice checkboxes in the category meta box to exclusive radio buttons. This prevents users from accidentally or intentionally selecting more than one category for a post.

Simplified Editor Interface: Reduces user confusion and potential errors by presenting a clear, mutually exclusive choice for categorization, streamlining the content creation workflow.

Taxonomy Integrity: Helps maintain a clean and logical site structure by ensuring posts are not cross-listed in multiple categories, which can improve navigation and content discoverability.

Lightweight Implementation: The plugin performs a specific, focused modification to the admin interface without adding complex settings or configuration panels, minimizing performance impact.

Backward Compatibility: Works with the standard category system and does not alter existing data, only changing the user interface element for selecting categories on new and existing posts.
