   BLOG · LA ENTRADA (templates/blog-entrada.php)
   Copia de material/mockup-blog-entrada.html: barra de lectura, cabecera,
   portada, texto con índice fijo, compartir, autor y «Sigue leyendo». Las
   piezas del texto, en 25-blog-bloques.css (de ahí salen los --bb-*).
   La cabecera del sitio mide 76 px (64 px hasta 980 px): de ahí el sticky
   del índice y el margen de los anclajes.
