   COMPONENTS · CHECKOUT — the layout & furniture of the transaction's arc: the
   review-before-buy shell (a reading column with a sticky order aside), the
   signed-in identity strip that keeps account + purchase one act (no double
   wall), the framed offprint identity, and the two post-Stripe landings that
   complete the arc into the unlocked content. Everything else composes the
   built system (order-summary, assessment, provenance, stamp, badge, process,
