/* Estilos de portada — compartidos por las dos verticales.

   Vivían dentro del {% block head %} de templates/index.html, así que la portada de la
   segunda vertical (templates/comercial/index.html) se dibujaba SIN ellos: el hero salía
   alineado a la izquierda y las tarjetas sin caja. Sacarlos acá los deja en un solo lugar
   para las dos y evita que la próxima portada nazca con el mismo problema.
