   CSS spec trap: `overflow-x: hidden` on ANY element implicitly promotes its

   into a vertical scroll container with its own OS-native scrollbar.
   .brand-page, .collection-page, and similar wrappers all use overflow-x:hidden.
   When the overscroll engine translates <main> downward, those containers detect
   overflow, show a ~15px scrollbar, and shift the content left.
   Applying scrollbar rules universally catches every element, regardless of
   whether it becomes a scroll container through explicit or implicit CSS spec promotion.
