科幻节点选择音

Dry sci-fi node select tick, 100 ms. A single short filtered metallic tick with a faint digital data-blip texture on the tail, same steel family as the global UI click but with a colder, more digital sheen. Dry, precise. No reverb, no musical pitch, not a computer beep. Finish within the stated duration; do not repeat. Peak around -6 dBFS, no clipping.
