/**
 * Widget de subida de fotos del DNI. Compartido por la pagina de registro
 * (session/join) y la de re-subida tras rechazo (session/uploadDni).
 *
 * El comportamiento vive en /js/dni-upload.js. Antes este CSS estaba duplicado
 * en las dos plantillas Volt y ya habia divergido (min-height, padding, iconos).
