A deep crack echoes; she freezes, slowly raises her head toward the sound, and whispers, \"Did you hear that?\" A few tiny ice crystals drift down through her headlamp beam. The camera gently pushes from a waist-up view into her concerned face; keep the geography and her identity stable. Realistic breath vapor, subtle human expression, detailed blue subsurface light. Native stereo cave echo and quiet ice creaks, clearly synchronized brief English speech. Five seconds, restrained action, no collapse. No subtitles, logos or on-screen text.",
