   MsUpload 图标重影终极净化 (针对 Citizen 皮肤优化)
   ========================================================================== */

/* 1. 全局清理：剥夺该组件内所有元素的“绘图权” */
#msupload-select,
#msupload-select *,
#msupload-select *::before,
#msupload-select *::after {
    background-image: none !important;
    -webkit-mask-image: none !important;
    mask-image: none !important;
    content: none !important;
    background-color: transparent !important;
}

/* 2. 局部重建：只给最内层的图标元素恢复单次渲染 */
#msupload-select span.oo-ui-icon-upload.oo-ui-iconElement-icon {
    display: block !important;
    /* 强制指定图标路径 (使用系统标准路径) */
    -webkit-mask-image: url(/resources/lib/ooui/themes/wikimediaui/images/icons/upload.svg) !important;
    mask-image: url(/resources/lib/ooui/themes/wikimediaui/images/icons/upload.svg) !important;

/* 3. 暗色模式适配：如果你的维基开启了暗色模式，图标需要变白 */
.mw-layout-context-dark #msupload-select span.oo-ui-icon-upload.oo-ui-iconElement-icon {
    background-color: #f8f9fa !important;

/* 4. 容器对齐修正 */

    justify-content: center !important;
