  Modal de "Generar ticket de pedido": formulario de datos de contacto →
  envío a la Cloudflare Function /enviar-pedido → confirmación con folio.
  Ver docs/ARCHITECTURE.md#flujo-de-un-pedido para el flujo completo.

  Mismo patrón visual/de animación que .order-sidebar en mobile: siempre
  en el DOM, oculto por defecto vía opacity/pointer-events, revelado con
  la clase .is-open. z-index por encima del sidebar de pedido (300+) para
  que el modal quede arriba incluso si el panel mobile del sidebar está
  abierto detrás.
