Function
The hrefs for step 1, step 2, what follows step 2, and the end of the onboarding
A course route that sent the learner to the onboarding names itself in
next. When that value is a safe course path, both steps carry it forward
and the onboarding ends there; otherwise it is ignored: step 2 continues to
the first-course step, and an already onboarded learner lands on My
learning, exactly as when opened from the landing.
Resolves the onboarding's destinations from the
nextquery parameter.
