  Below I show how two real clocks in the real world can be
synchronised, strictly according to Einstein's method.
 We have to equal clocks C_A and C_B. They are not synced in any way,
but they are using the same time unit, let's call it second.
The clocks run at the same rate.

This is a self-contradicting statement!
'Synchronization' does not mean 'to turn the clocks to the same shown time once'.
Instead 'Synchronization' means 'adjust both clocks, that they are maintaining to show the same time'.
One part of the procedure would be to adjust the readings.
But the other part would be to adjust the tick-rate, hence the length of the second.
We could simply discard 'adjust the reading' from our todo list, at least for while, because upon our home-planet we have also time-zones.
That would leave 'adjustment of the tick-rate' as main requirement for synchronization.
But you have already preassumed, that this adjustment was already made. (with " The clocks run at the same rate.")
This would violate your statement, that both clocks are not synchronized.
