Function
Goes in LearnerCard's nameField slot, where it replaces the name the
card would otherwise print. It is styled to read as a field rather than as
the card's own text — a resting dashed line, a caret, and a solid gold line
on focus — because a card that only previewed the name sent learners
clicking at text that could not answer.
Both onboarding steps use it, so the card's name can be written on step 1 and corrected on step 2 without leaving the card.
The learner card's name, written in place.
