Is there any way to use Qualtrics to assign research participants into four between-subjects conditions WHILE ALSO keeping the gender ratio for each condition roughly balanced?
Assuming I collect gender information as the first question on a survey, is there some way to use quotas or randomiser features or display logic to make this happen? I have tried to think it through but can't think of any way to do this.

How can I use Qualtrics to randomise participants into 4 conditions while keeping gender ratio even?

This seems pretty straightforward. You need 2 branches in your survey flow. 1 IF male and 1 IF female (however you define that in your data).
Then nest a randomizer block under both branches and use the randomizer to assign 1 of the 4 conditions evenly (make sure to check "equal present" 1). Both branches should look identical, with the only difference being the Male/Female branching logic.
This will make sure to assign each condition evenly among the genders, so that, assuming you have an even gender split, your responses will be evenly represented.
Note, if you have something like 40 males and 60 females, then you will still get an even distribution of the conditions within the genders, but your results will skew slightly higher for females.
If you want to control this further, you can use Quotas to cap the number of responses from each condition and gender.
