Complete codebase access allows unlimited customization and feature development. The modular architecture separates core functionality, configuration, and content into distinct layers. Templates, snippets, and blueprints use PHP with clear documentation and logical organization. Custom CSS and JavaScript injection happens through dedicated admin panel controls or file includes. The system supports local development using built-in PHP servers, MAMP, XAMPP, or Docker environments. Git-friendly structure enables version control for custom development. AI-assisted development works seamlessly with tools like Claude or Cursor that can read and modify the codebase. The standalone content blocks plugin demonstrates the extensibility model. Debug mode provides detailed error reporting during development. For developers, the clean architecture and documentation reduce the learning curve while maintaining flexibility for complex implementations.
