Premium Tech Launch Poster Prompt

Create a premium tech launch poster for the fictional product [PRODUCT NAME], hero device or interface floating in dark space. Vertical 4:5 composition. Composition: the hero product floats centered in the frame against a deep dark background with sleek gradient washes of color flowing behind it — deep indigo fading into electric cyan, or warm amber fading into magenta, your choice per launch. Glowing edges trace the product silhouette with a soft luminous rim. Typography: clean modern sans-serif. A short bold headline at the top, a one-line supporting subhead beneath it, and three small feature callouts arranged around the product with thin connector lines — each callout one short line naming a key capability. Keep all copy minimal, legible, and perfectly spelled. Mood: futuristic, premium, cinematic. Soft volumetric glow, subtle lens bloom, controlled reflections under the floating product. No clutter, no busy UI elements, no random decorations. The product is the sole star; negative space does the rest. Render quality: ultra sharp, high detail, photorealistic product rendering, professional advertising finish, 8K.
