 * iSieve Arkhe Child Base - block editor utility classes
 *
 * How to use:
 * 1. Add the class from the block editor: Advanced > Additional CSS class(es).
 * 2. Combine classes when needed, e.g. "isv-section isv-section--soft isv-align-wide".
 * 3. Keep page-specific CSS in the bottom section or inc/custom.php only when CSS cannot solve it.
