Maybe say that.  If there is a good reason why you
would define some "variables that affect frame
appearance" in the early file then maybe provide
that.

It's not because one _can_ define variables there
that one should do so, in general.  But if there
are particular cases where it might be _better_
to do it in the early file then maybe mention them.

In general, it needs to be made clear why you might
better put something in the early file (and perhaps
give some examples), and state the general guideline
that otherwise you should put everything in the
"late" file.
