📝 DESCRIPTION

The Desaturate node transforms a full-color texture into a grayscale version.

The luminance calculation uses the following formula:

Gray = 0.2989 * Red + 0.5870 * Green + 0.1140 * Blue

Ideal for previews, stylized effects, or preprocessing steps in visual pipelines.

This node is derived from BaseImageNode.
