科幻终端点击音

Short dry sci-fi UI click, 90 ms total. A tight metallic tick — like a fingernail tapping a thin steel plate — layered over one soft 110 Hz sine sub-thump, with a very short neon-cyan glass shimmer tail that decays in 40 ms. Cold, precise, tactile, industrial terminal feel. No reverb, no musical pitch, no bell tone, no cinematic or orchestral elements.
