Bulgeless galaxies trace the upper envelope of the mass-R1 relation with scatter driven by central stellar density and the spatial configuration of mergers rather than their number.

The Big Wheel at z~3 has a stellar-to-halo mass ratio of 0.06, higher than expected, implying efficient stellar assembly without major mergers or instabilities.
Bulgeless galaxies in TNG50 form later, maintain high disc fractions since z~1, and preferentially experience gas-rich coplanar mergers that preserve discs, unlike bulge-dominated galaxies.
