Submarine Hull Stress Warning

One complete 3-second hull stress warning sound effect for a deep-sea metal exploration capsule. Begin with a short strained metal hull creak, then a restrained cabin warning tone, followed by a low structural resonance and a natural fade. The warning must cut through thick underwater ambience while remaining muffled and industrial, not bright or arcade-like. This is one single event with no voice, no music, no explosion, no repeated collision and no ambient background.
