negative margins?) and use transparency in their background to achieve
the fade effect?  If so, then you just use scroll-snap-margin with
negative values to shrink the snapping bounds of the element back to
the desired rectangle, and align them however you wish - probably
'center'.  This doesn't actually invoke the "unreachable snap
position" stuff, except maybe accidentally if there are rounding
errors and the first element's snap position ends up technically
slightly outside the scrollable area.  (This kind of possible accident
is one of the reasons snapping to out-of-viewport positions is
