On mobile\r\n * the gallery is a Swiper slider, and Swiper's default `preloadImages: true`\r\n * downloads every <img> inside the slider when it is created, before the theme\r\n * filters the gallery to the selected color: on PDP 80000 that is 149 photos\r\n * plus 149 thumbnails (about 5 MB), ignoring loading=\"lazy\".\r\n *\r\n * This turns preloading off for sliders inside <media-gallery> only (product\r\n * page and quick view). The browser then loads the visible photo, and the next\r\n * ones as they come close (native lazy loading). Other sliders on the site are\r\n * not changed.\r\n *\r\n * Load with defer right after vendor.js (which defines MinimogLibs.Swiper) and\r\n * before theme-global.js / product-media.js create any slider.\r\n */\r\n(function () {\r\n  'use strict';\r\n\r\n  var libs = window.MinimogLibs;\r\n  var OriginalSwiper = libs && libs.Swiper;\r\n  if (typeof OriginalSwiper !== 'function' || OriginalSwiper.__ibkGalleryNoPreload) return;\r\n\r\n  var GALLERY_SELECTOR = 'media-gallery, media-gallery-mobile';\r\n\r\n  function isGallerySlider(el) {\r\n    return !!(el && typeof el.closest === 'function' && el.closest(GALLERY_SELECTOR));\r\n  }\r\n\r\n  class GallerySwiper extends OriginalSwiper {\r\n    constructor(el, params) {\r\n      if (isGallerySlider(el)) {\r\n        params = Object.assign({}, params, {\r\n          preloadImages: false,\r\n          updateOnImagesReady: false\r\n        });\r\n      }\r\n      super(el, params);\r\n    }\r\n  }\r\n\r\n  GallerySwiper.__ibkGalleryNoPreload = true;\r\n  libs.Swiper = GallerySwiper;\r\n})();\r\n"],
