One onboarding journey
Onboarding now follows one supported journey, using saved progress to resume incomplete setup without falling back to the retired profile flow.
Onboarding now has one supported entry point. Learners who have not finished setup resume the canonical journey from their saved state, while learners who have completed or skipped it continue to their requested destination.
- The retired profile-based onboarding route and its deployment switch have been removed.
- Navigation no longer carries compatibility-only locking behavior.
- Rollback remains available by redeploying the last approved frontend revision.
