Answer 1

Sembra che il nodo titlerecdovrebbe essere il rettangolo creato con il \fillcomando iniziale . Possiamo sostituirlo con un nodo utilizzando la libreria tikz fit ei nodi della pagina da tikzpagenodes per risolvere il problema.

Il codice seguente ora viene compilato senza errori per fornire l'output desiderato. Naturalmente, inizialmente, il duro lavoro è stato svolto nel posthttps://tex.stackexchange.com/a/374634/134144. Detto questo, ho razionalizzato il codice, fatto un uso migliore di tikzpagenodes , reso coerenti le versioni numerate e innumerevoli e ho tolto del codice che ritenevo non necessario. Fatto ciò, il codice produce:

Ecco il codice aggiornato:
