  2. Step 2: The framework must 'absorb' seismic shocks and prevent structural 'collapse'.
Answer
absorb ... collapse.
Why not the others: 'amplify ... integrity' contradicts engineering goals by worsening vibrations; 'resist ... perfection' is nonsensical; 'ignore ... elevation' does not fit structural dynamics.
