    "body_text": "The analysis extends deep thermalization from pure projected states to noisy mixed states and finds universality independent of microscopic unitary details in the studied regimes. Numerical checks include qubit circuits and kicked Ising dynamics. It is a theoretical and simulation result, not a hardware demonstration.",
