   Sistema visual compartido por las fichas del portafolio. Toma el lenguaje
   de la pagina de Servia (hero a dos columnas, secciones alternas con
   antetitulo, tarjetas de vidrio) y lo generaliza para proyectos que no
   tienen capturas reales: en lugar de la captura, el hero muestra una
   maqueta compuesta con CSS.

   Ojo: Orbitron (--font-heading) no dibuja bien la enye. Evitar esa letra
   en los titulos que usan esa familia.
