[vgtkfppp] Jury nullification prevention

What aspects of courtroom procedure and the entire juror "experience" are put in place to discourage a juror from exercising jury nullification?

I am vaguely aware of three.  Jury selection somehow weeds out those likely to exercise nullification.  Architecture and formal procedures somehow convey a feeling of awe to encourage respecting the system and not to break it.  Jurors are somehow steered toward judging only the veracity of the alleged facts of the case, and not to judge the law which prescribes a decision once the facts are established.

I would like specifics of how these work (e.g., what is said, what is asked, what is done) as well as others I don't know about.

While day-to-day cases are fine, I am in particular interested in any special procedures that might happen only for very important potentially precedent-setting cases.  I have never heard of jury nullification occuring in any such landmark case.
