Just on that point, the simpler answer is: on desktop, when zooming, the
browser reflows content (if the content is responsive/adapts to the
width of the window). On mobile/tablet, there's an additional viewport
that determines the "logical" width of content, and any zooming that
happens with pinch-to-zoom then zooms into that without any additional
reflow.
