How access works

Billing status stays separate from product access.

The account area reads product access. Checkout and webhook events update billing status first, then access is granted or removed.

01Passwordless account first

Users log in with email links before checkout or account access.

02Provider checkout owns payment

When real checkout is enabled, provider webhooks update account billing status.

03Product access decides entry

Product apps check active account access, not raw payment-provider state.
