 * son los mismos del sitio (copiados de flota.html) para que el blog no se
 * sienta como otra web. Todo lo editorial (portada, prosa, cajas, FAQ,
 * fuentes, relacionados) vive aquí y se reutiliza en cada artículo nuevo:
 * un artículo no debería necesitar CSS propio.
 *
 * Rutas: las páginas del blog cuelgan de /blog/, por eso todos los recursos
 * van con ruta absoluta (/fonts, /img, /nf-blog.css).
