SR does not describe time compression.
That you made up. According to SR, A's change it frames will
result in A seeing B's age jump forward.

Wrong. SR has nothing to say about non-inertial frames.

Special relativity (SR) (aka the special theory of relativity) is the
physical theory of measurement in inertial frames of reference
proposed in 1905 by Albert Einstein in his article "On the
Electrodynamics of Moving Bodies".

Reading the page you cite, we find:

Special relativity does not account for gravity, but
it can deal with accelerations.

How does special relativity deal with accelerations?

Cyclotron experiments have shown that, even at accelerations of 10^19
g (g = acceleration of gravity at the Earth's surface), clock rates
are unaffected. Only speed affects clock rates, but not acceleration
per se.
