/**
 * A CHECKOUT'S SIGN-IN KEEPS THE CHECKOUT, AND GOES BACK TO IT.
 *
 * pay sends a buyer with no session to sign in with the checkout as `?next=`
 * (hanzo-inc/pay lib/auth `login`). A campaign's checkout carries its plan, a
 * coupon and the campaign's tags. The sign-in page is that checkout's first
 * step (components/auth/page.tsx, lib/auth/sale): /login stays the sign-in, so
 * a returning customer is one step from the checkout, the offer is said across
 * the top in pay's words from commerce's quote, and the controls are pay's 56px
 * at 16px. Every way in — a provider through IAM's authorize, a
 * new address proven by a code, a known one by its password — lands on the
 * checkout exactly as it was asked for (components/onboarding/flow.tsx), past
 * the terms where IAM says they are owed.
 *
 * IAM and commerce are answered here (./issuer, the quote below); what is
 * measured is the page, and the address the browser ends on.
