Counts each parent, co-parent, and kid separately — not one count per family.
All-time, real families, excludes sandbox and comp/offer-code $0 events.

Codes generated vs. successfully redeemed. A low rate here means kids are hitting wrong/expired codes — each failed attempt also used to leak a permanent orphaned account (fixed 2026-08-17).
