1 Introduction Collective electronic states are highly sensitive to underlying lattice symmetries and superlattice modulations, providing practical knobs to reshape and tune broken-symmetry phases such as charge order and superconductivity. Two-dimensional (2D) materials are especially well suited to such control, and recent progress using twisted layers [1-3] and patterned substrates [4, 5] highlights how engineered periodic potentials can be used to tune correlated phases [6].
