Enroll with the right context

Task sequence

• Resolve whether registration is open and whether the visitor is the owner.
• Keep the header action aligned with the enrollment panel.
• For a guest, carry the course destination through registration/sign-in.
• For a free class, enroll through the appropriate app request.
• For a paid class, proceed to the checkout destination returned by the app.

Data and persistence boundary

SignupSidebar controls free versus paid behavior; EmailCodeAuth restores a safe callback and can continue a free enrollment. Displayed price and countdown do not authorize payment or determine access by themselves.

Failure and recovery

Pending and error states belong beside the enrollment action. Closed registration should not be bypassed by an out-of-date header CTA.
