Both of today's image repairs trusted an authored fixed size as the
design's intent. A weak model routinely drops a 400x300 plate into a
390px phone card and CROPS it - which looks right - so the rail repair
widened every card to 400 (one card ate the screen, the rest clipped
away) and the band repair grew every photo band to 300 (a wall of empty
space under each deal). Both now demand that the number be plausible for
the slot it is in: a card is starved only when it is genuinely unusable
and its demand still leaves the rail scrollable, and a band only takes a
photo's height when the result is not taller than the band is wide.
Oversized plates go back to the fixer that shrinks them.
