Content starts with one pre-created "Section 1" (0 Activity sheets), an "Add Section" button, and a "Choose a template" shortcut.

Drip Settings (under course Settings, 5.8) controls when that content becomes visible to learners: Immediately after enrolling (the default), After X days of learner enrollment, or On a specific date. This is a Group-course-specific pacing control; 1:1 courses don't have an equivalent.

Landing Page is a public, self-serve sign-up-and-pay page — a course image, a "Your details" form (Name / Email / Phone), and a Pay button. This is the actual destination behind "Share invitation" (5.3): a learner with the link lands here, fills in their details, and pays, without an admin touching the enrollment wizard at all.
