/*
 * Shared "filter dropdown" component styling — a custom popup menu (white
 * card, rounded corners, shadow, blue checkmark on selected items) used in
 * place of the browser's native <select> popup on every list-page filter
 * across the app. Enhancement is applied by public/js/filter-dropdown.js.
 *
 * Markup contract (see resources/views/components/filter-dropdown.blade.php):
 *   <div class="filter-dd">
 *     <i class="... filter-dd-icon"></i>
 *     <div class="filter-dd-field">
 *       <span class="filter-dd-label">Label</span>
 *       <select class="filter-dd-select" ...>...</select>   (single or [multiple])
 *     </div>
 *     <i class="ti ti-chevron-down filter-dd-chevron"></i>
 *   </div>
 * A .filter-dd-checkboxes variant (real checkboxes instead of a <select>)
 * is also supported for filters that were already checkbox-based.
