* Dynamic Loading System Testing Suite
*
* NOTE: This test suite currently tests the basic functionality available
* in the current Leptos demo app. Many advanced features like dynamic
* component loading, search/filter, and favorites are not yet implemented
* in the main UI.
*
* Tests are adapted to work with the current implementation while maintaining
* the testing structure for future enhancements.
