Cover is reused Volt alley card art from examples/gallery/combine-images/preview.webp (wet neon alley), pending a true Stable Audio 3 Small Music QC bed — no paid stable-audio-3/small/music/text-to-audio or NanoGPT run this PR. No fake waveform thumb. Job is an instrumental stereo night-ride bed: late-night neon alley score for a charcoal Volt pocket radio with a cyan lightning chevron; low trip-hop pulse, soft rain ticks. Distinct from Closing-credits song (sing / Mureka generate-song), Night-ride SFX (elevenlabs/sound-effects/v2), Night-ride radio VO (xai-tts), and Mirelo video foley. Open the graph — Score brief is the Volt alley sentence; Score pins stable-audio-3/small/music/text-to-audio with instrumental true (~$0.024/gen). No vocals, no lyrics. No upload. No LLM.
