public sealed class HorizontalLineDrawer : PropertyDrawer

Renders a solid-color horizontal separator line above the decorated property field. The line color and thickness are configured through the HorizontalLineAttribute constructor. A fixed vertical padding of PADDING pixels is applied on both sides of the line so that it does not crowd adjacent Inspector elements.
