I appreciated the information being presented, but when the controls are not visible at the same time as the thing they effect it makes the interactive component almost worthless.

same, OP you should put the source image and controls in a floating popover that's static while the rest of the page content is scrolled, or a sticky header or something.

What configuration did you use to pass the test? I guess I couldn't think illogically enough.

I removed one of the cross coupled outputs (only one NOR was connected to the other, not both outputs cross coupled) and magically it worked. Didn’t make any sense from a logic perspective though.
