/* Motion for the order app mockup, from the transitions-dev skill (.claude/skills/transitions-dev).
 * Only the tokens and the three snippets used here are copied (not the whole library).
 * Used: 04 text states swap (price badge), 08 page side-by-side (step switch; state hook adapted
 * from data-page="1|2" to data-pos="before|current|after" so it works for three steps), 22 toast (WhatsApp placeholder; the "Link copied" use went with the save-link panel, 2026-10-21).
 * Custom (nothing in the library fits a per-card 2 s hint): the dimmed card "COMING" tag fade, 150 ms.
