 /**
 * @class ScreenSaver
- * @brief Animated starfield screensaver widget for system idle periods
- * @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.

-     *          - Preparing graphics context for efficient rendering
-     *          - Initializing the animation counter for smooth timing
-     *          - Allocating and positioning all star objects
-     * 
-     * During initialization, all stars are placed at random positions within
-     * the 3D space defined by Z_NEAR and Z_FAR constants. Each star receives
-     * random x, y coordinates and a z-depth that determines its movement speed
-     * and visual appearance. The animation system is prepared for immediate

-     * @brief Initializes the button handling subsystem and configures hardware
-     * 
-     * @details This function sets up the complete button handling infrastructure:
-     *          - GPIO configuration for button input pins with pull-up resistors
-     *          - Interrupt service routine installation for responsive input
-     *          - Debouncing timer creation and configuration

-     *          - Button state tracking structure initialization
-     * 
-     * The function configures all defined button pins to trigger interrupts
-     * on both rising and falling edges, enabling detection of both press
-     * and release events. Each button uses a dedicated timer for debouncing
-     * to ensure reliable input processing even with mechanical switch bounce.
-     * 
-     * Button events are queued using FreeRTOS queues to ensure no input
-     * events are lost during high system activity periods. The queue-based
-     * approach also decouples interrupt handling from application processing.
-     * 
-     * @pre ESP32 GPIO and timer subsystems must be available and functional
-     * @pre FreeRTOS must be running and queue services available
