<?php
/**
 * Rename GravityView "Workflow Complete" to the Actual Step Name
 *
 * GOAL:
 * - When GravityView displays the status "Workflow Complete", replace it with the configured
 *   Workflow Complete step name from Gravity Flow for selected forms.
 *
 *
 * CONFIGURATION:
 * - Update $form_ids below to the list of form IDs this should apply to.
 *
 * NOTES:
 * - Runs only when the field value is exactly "Workflow Complete".
