	Calculates the rectangle occupied by the custom cursor. Determines the cursor's position based on the text content and cursor position, and returns a QRect representing its visual bounds.
	CyberLineEdit (QWidget *parent=nullptr)
	Constructs a CyberLineEdit. Initializes the widget with cyberpunk styling (border, background, padding, font) via stylesheet, sets the text color, cursor type, minimum height, and starts a timer for the custom cursor blinking animation.
double	GetGlowIntensity () const
	Gets the current intensity of the glow effect.
void	SetGlowIntensity (double intensity)
	Sets the intensity of the glow effect. Triggers a repaint of the line edit.
QSize	sizeHint () const override
	Returns the recommended size for the line edit. Enforces a minimum height of 30 pixels.
	~CyberLineEdit () override
	Destructor. Stops the cursor blink timer.

Protected Member Functions
void	enterEvent (QEvent *event) override
	Overridden enter event handler. Animates the glow effect partially in if the widget doesn't have focus.

double	glowIntensity
	Property controlling the intensity of the border glow effect (0.0 to 1.0). Animatable.

Private Attributes
QTimer *	cursor_blink_timer_
	Timer controlling the blinking animation of the custom cursor.

Detailed Description

A custom QLineEdit styled with a cyberpunk aesthetic.

This line edit features a dark background, clipped corners, a neon blue border, and a subtle glow effect that animates on focus and hover. It also implements a custom-drawn blinking cursor instead of the default system cursor.
