A "buy and use" suggestion: the viewer doesn't have a covering membership or pass, but the business sells passes that would work for this session. Carries the candidate passes the client should offer in its inline pass picker. Filtered server-side by business, visibility, sale window, and (for passes flagged purchaseRules.introOffer) by ownership; signed-out viewers never see this option because pass purchases require an account. Suppressed when the viewer already has a covering pass or membership option in this resolution.
