* @details This final class inherits from Widget and implements an interactive
* screensaver featuring an animated starfield effect. The screensaver
* activates automatically during periods of user inactivity to prevent
* screen burn-in while maintaining visual indication of system activity.
*
* The ScreenSaver class provides:
* - Dynamic starfield animation with pseudo-3D depth effect
* - Configurable star count and animation speed parameters
* - Automatic activation during idle periods
* - Immediate deactivation on any user input
* - Smooth star movement and regeneration system
* - Memory-efficient star management with object pooling
*
* Key features include:
* - 3D-style starfield with depth-based speed variation
* - Continuous star recycling for infinite animation
* - Responsive user input handling for immediate exit
* - Optimized rendering for smooth animation performance
* - Configurable animation parameters for different visual effects
*
* The starfield effect simulates movement through space by moving stars
* from the center outward at speeds proportional to their depth (z-coordinate).
* Stars that move beyond the screen boundaries are automatically recycled
* to new random positions, creating an infinite scrolling effect.
*
* @note This class is marked as final and cannot be inherited from.
* @note The screensaver automatically exits on any button press, returning
* control to the previous screen or main menu interface.

* - Moving stars outward from center based on their z-coordinate
* - Recycling stars that move beyond screen boundaries

* - Resetting off-screen stars to new random positions near the center
* - Applying speed multipliers for smooth, consistent motion

* - Applying perspective projection to simulate depth
