 * Create a watermarked shader preview from a preview token or preset ID.

 *
 * @example
 * ```ts
 * const preview = await createPreview(canvas, {
 *   presetId: 'abc123',
 *   configuration: { primaryColor: '#ff0000', intensity: 0.5 }
 * })
 *
 * // Update configuration at runtime (no refetch)
 * preview.setConfiguration({ primaryColor: '#00ff00', intensity: 0.8 })
 *
 * // Cleanup
 * preview.destroy()
 * ```
