 * instead, same-origin. Shared by everything in this project that calls a
 * REST endpoint directly instead of going through a block attribute.
 *
 * The root falls back to `MasteriyoDivi5ModulesData.restRoot`, localized
 * onto this same app window from `rest_url()` by d5-loader.php — not to a
 * `location.origin`-based guess, which is wrong whenever WordPress is
 * installed in a subdirectory.
