/* =====================================================================
   Custom Gallery Modal (CGM) — استایل مستقل و قابل استفاده مجدد
   یک پاپ‌آپ گالری تمام‌صفحه با دو تب «تصاویر» و «ویدئو»، بدون وابستگی
   به هیچ کتابخونه‌ی شخص ثالثی (PhotoSwipe / fancybox و ...).

   نحوه استفاده:
   1) این فایل رو لینک کن:      <link rel="stylesheet" href="custom-gallery-modal.css">
   2) custom-gallery-modal.js رو هم لینک کن (بعد از jQuery).
   3) مارک‌آپ HTML مودال (بخش #customGalleryModal) رو از پروژه‌ی اصلی کپی کن.
   4) CGM.open($product, 'images' | 'video') رو صدا بزن.

   نکته: کلاس‌های .video-popup-inner / .video-popup-file / .video-popup-embed
   برای نمایش محتوای ویدئو (تگ <video> یا آیفریم Embed) داخل تب ویدئو هستن.
