 * A shader node that provides instance IDs attribute functionality.

 * The node supports both WebGL (GLSL) and WebGPU (WGSL) shader backends.
 *
 * @example
 * ```typescript
 * const instanceIdsNode = new AttributeInstanceIdsShaderNode();
 * // Use in a material's shader graph for accessing instance-specific data
 * ```
