Global Metadata
Genre: cyberpunk UI alert / neon synth ringtone. BPM: 140. Key: F# minor. Cold, digital, futuristic. Ultra-short notification blip.
Application: a half-second phone ringtone made of pure electronic signal design — think Blade Runner UI chirp, not a jingle sung by a person.

Vocal Details
STRICTLY NO HUMAN VOICE. No singing, no hummed notes, no vocoder voice, no choir, no breath, no mouth sounds, no syllable-like tones. Zero vocal content of any kind.

Arrangement
Pure synthesized cyberpunk stinger only: sharp neon square/saw blip, glassy digital ping, or FM bell glitch — machine-made, not voice-like. No drums bed, no bass groove, no pads. Dry, punchy, electronic, ringtone-length. Sound like hardware firmware, not a singer.
