I would prefer that we use the features of material to try and keep some ux design consistancy. Either changing the variant to outlined or filled, using InputProps. Putting the label separate in a stack is drifting from the overall design system farther than I'd like.

Sounds good. I think I misunderstood the intent of our planning meeting decision:

Modify the presentation of the Find a domain search box so that it appears as a label followed by the textbox.
