/* ============================================================================
   SPICA STUDIO · r26 · POPUP DE BIENVENIDA POR INDUSTRIA

   Hoja nueva, cargada SOLO en las dos portadas. No redefine ningun token y no
   pisa ninguna clase de sections.css, chrome.css ni responsive.css: todo lo de
   aqui cuelga del prefijo `.welcome`, salvo la clase de bloqueo de scroll
   `html.welcome-lock`.

   El lenguaje visual es el de la casa: papel, filete de un pixel, radio grande
   y el mismo enlace mono en versalitas de `.pin-slide__more`. Lo unico oscuro
   es el velo del fondo y la foto de cada tarjeta, que necesita un degradado
   para que el nombre de la industria se lea encima.

   Los bloques responsive van al final y en orden DESCENDENTE de ancho, como el
   resto del sitio: cada uno pisa al anterior en su tramo.
