Cover is reused Volt courier card art from examples/gallery/talking-avatar/preview.webp (night dispatcher), pending a true SpaceXAI TTS QC take — no paid xai-tts or NanoGPT run this PR. Job is speech only: Spoken script → Speech (`xai-tts`, voice Leo). First-click is a Volt night-board dispatch callout. Distinct from Spoken introduction (talking-avatar / Muse + MiniMax Speech + LongCat), Night-ride radio take (infinitetalk-radio-take), Night-ride SFX (elevenlabs/sound-effects/v2), and Closing-credits song (sing / Mureka). No image, no video, no LLM, no upload. Open the graph — Spoken script is the Volt callout; Speech pins xai-tts at voice Leo (~$0.0023 / well under $0.01). Custom-endpoint stays retired.
