Public Member Functions
	CyberpunkButton (const QString &text, QWidget *parent=nullptr)
	Constructs a CyberpunkButton. Initializes the button's appearance (stylesheet for text, colors, size policy), sets up the text glow effect (QGraphicsDropShadowEffect), and configures the QPropertyAnimation for the hover glow effect.
qreal	GetGlowIntensity () const
	Gets the current intensity of the glow effect.
void	SetGlowIntensity (qreal intensity)
	Sets the intensity of the glow effect and updates the button's appearance. Modifies the text glow effect's blur radius and color alpha based on the intensity. Triggers a repaint of the button.
	~CyberpunkButton () override
	Destructor. Cleans up allocated animation objects.

Protected Member Functions
void	enterEvent (QEvent *event) override
	Overridden enter event handler. Starts the animation to increase glow intensity.
void	leaveEvent (QEvent *event) override
	Overridden leave event handler. Starts the animation to decrease glow intensity.
void	paintEvent (QPaintEvent *event) override
	Overridden paint event handler. Draws the custom cyberpunk button frame. Calls the base class paintEvent first, then draws a rounded rectangle frame whose color alpha and thickness depend on the current glow_intensity_. Optionally draws a secondary outer glow for the frame at higher intensities.
void	resizeEvent (QResizeEvent *event) override
	Overridden resize event handler. Currently only calls the base class implementation.

Properties
qreal	glowIntensity
	Property controlling the intensity of the button's glow effect (0.0 to 1.0). Animatable. It affects the brightness and thickness of the frame border and the text's drop shadow.

Private Attributes

	Animation controlling the glowIntensity property on hover.
QColor	glow_color_
	Base color for the frame's outer glow (alpha adjusted by glow_intensity_).

	Current intensity of the glow effect (0.0 to 1.0). Controlled by glow_animation_.

Detailed Description

A custom QPushButton styled with a cyberpunk aesthetic, featuring animated glow effects.

This button provides a distinct visual style with a neon blue frame and text. It includes a glow effect for both the frame and the text, which animates smoothly on mouse hover (enter/leave events) using QPropertyAnimation. The intensity of the glow and the thickness of the frame adjust based on the animation state.
