Concerns: The application relies on an SDL2 display; running the container to exercise the UI will require a display or a dummy/simulated video driver (e.g., SDL_VIDEODRIVER=dummy) to avoid failures in headless environments., No non-root user is configured; running as root may be a security consideration for production use.

Concerns: The CMD runs a GUI application (SDL2) and may fail or hang in headless environments or CI without a display. Consider using a non-GUI test or setting SDL_VIDEODRIVER=dummy for smoke tests., Running the built binary directly could require an X server; if this container is intended for automated smoke tests, ensure the environment supports SDL displays or disable the GUI path during testing., The dummy 'file' utility is a placeholder; document its purpose and ensure it won't mask real file-type checks if needed in future tests.
