The preferred-scale lookup reaches well past the byte-normalization cases it was
added for: any value that is exactly n/2^k for a k the old denominator limit
could not reach now prints as a fraction, so constants that used to be short
exact decimals changed shape. That is the widest-reaching part of the change and
nothing pinned it.
The added constants are those values, including the unreduced 126 / 1024 that a
lowest-terms rewrite would turn into 63 / 512, plus two that must keep their
decimal form so the length gate stays covered from both sides.
