 * Validation runs on blur with a short shake and inline messages; an async
 * `onSubmit` drives pending → success (a drawn check with "Send another") or
 * an inline error that keeps every value. A side column holds channel cards
 * with copy-to-clipboard (the icon morphs to a check) and an office card with
