 * Plugin Name:       FP Genocide Maps

 * Description:       Manages the "Architecture of Genocide" maps shown on the home page. Each map is a post (title + description + image); the [geep_maps] shortcode renders the accordion + map image replicating the original Divi design, swapping the image when a toggle is opened.
