/* Buy flow — the external buyer's checkout shell.
 *
 * These pages are reached from a seller's own website by buyers who have
 * never heard of UseThatApp. The design mirrors the structure of a hosted
 * payment page (the pattern buyers already trust): the seller's app is the
 * only branded, colorful thing on the page; UseThatApp appears the way a
 * payment processor appears — small, quiet, in the fine print, linked to
 * its terms. No site nav, no marketing footer, no analytics, no framework.
 *
 * Type is the system stack on purpose: it is the native register of every
 * payment sheet the buyer has used, and it costs zero requests.
