/* PaperFlow · lecturas, biblioteca, temas y criterios editoriales (y la base del blog).
   Cada lectura es la pantalla de paper de la app nueva: el campo del color del
   tema arriba y la hoja de papel encima, con radio de 28. Las listas usan tapas
   de color, filas con el cuadrado del tema y bandas de borde a borde.
   Todo va con prefijo ed-: esta hoja también se carga en la portada y en las
   páginas informativas, que tienen selector de idioma. */
