In my experience page zoom not only changes the viewport with but also the scale factor. So the text size of sites is different at a width of 533 then it would be by zooming to say 150% that gets me to 533 (number made up) but also has a scale factor of 1.5.

I'm sure we've had this conversation many times before, but: using page
zoom effectively changes how many physical/screen pixels make up a CSS
pixel. So yes, full-page zoom will result in everything being bigger by
that factor, and the reported viewport width being smaller by that same
factor.

Do you have actual examples where this happens? Because it's not really
a given that responsive sites would cause more or less
cutoffs/overflowing, since every measure (be it a measure set in pixels,
or ems, or whatever) is scaled exactly the same way.

Do you have actual examples of a "truly fluid" site versus a "non-fluid
responsive" site?
