    • Enables fast iteration and easy integration into real-time 3D applications and game engines with minimal state synchronization and setup.
    • Use for creating in-engine debugging, profiling, and visualization tools in game development environments.
    • Use for building dynamic, code-driven content creation tools and editors that require rapid UI prototyping and iteration.
    • Use for embedding lightweight, portable GUI components in applications running on consoles, embedded systems, or custom platforms.
