/**
 * Dropdown layout for WooCommerce Extra Product Options "imagegroup" fields.
 *
 * Scoped entirely under .thwepo-imagegroup-select, which is only emitted by
 * get_html_imagegroup() in quarty-child/thwepo/class-thwepo-utils-field.php.
 * No other field type is affected.
 *
 * The rows deliberately do not carry the plugin's stock grid classes
 * (.thwepo-image-group-item etc.) — style.css sizes those to 46x46 swatch tiles
 * and hides their captions — so nothing here needs to fight inherited styles.
 *
 * Hovering an option's swatch shows the enlarged image; the card is appended to
 * <body> by thwepo-imagegroup.js because the panel's overflow would clip it.
