Enough that it never goes through the zero-crossing region ever.

What are you trying to say here? It dosnt make sense.

The problems with electrolytic linearity issues all have to do with
cases when there is very little voltage across the cap. So the
recommended design practice is to make sure there is sufficient DC
bias across the cap so that at any reasonable signal level, the cap
always has some voltage across it for any part of the waveform.
