(a) Entanglement entropy of eigenstates within an emergent subsector built from the root configuration for system size L = 26. This subsector has dimension 12 376 and is nonintegrable. (b) Entanglement entropy of eigenstates within an emergent subsector built from the root configuration for system size L = 26. This subsector has dimension 27 132 and is integrable. Red lines mark the Page value of the corresponding subsector.
