AI Tool Product Launch Hero

A full-bleed hero banner (1600×640 px) announcing an AI writing tool launch. Background: deep charcoal black with faint hexagonal mesh pattern. Center: a glowing orb composed of swirling cyan and violet neural-network filaments, slightly off-center to the left. Right side: large white sans-serif headline "Write Smarter. Ship Faster." below which a one-line subtext in pale gray reads "Powered by next-gen language models." Below that, a vivid cyan pill-shaped button with text "Try Free 14 Days". Thin neon cyan accent lines radiate from the orb like circuit traces. Lighting: the orb acts as the only light source, casting cool reflections on the dark background. Mood: futuristic, energetic, precise.
