/* ---------- Tablas de captura que se apilan en el teléfono ----------
   Las pantallas de conteo físico y recepción se usan de pie en la bodega, con el
   teléfono en la mano. Una tabla de 8 o 10 columnas con campos de captura obliga a
   desplazarse en horizontal mientras se escribe.

   Aquí la MISMA tabla se apila en pantallas pequeñas: cada fila se convierte en una
   tarjeta y cada celda muestra su encabezado a la izquierda.

   Importante: no se duplica el formulario. Renderizar dos versiones y ocultar una
   con display:none no serviría, porque los campos ocultos SÍ se envían y el último
   pisaría al primero: se perdería lo escrito. Por eso se resuelve solo con CSS. */
