Foldable Phone Launch Hero Banner

A wide 1920x600 hero banner for a foldable smartphone launch on an electronics marketplace. The hero device is a slate-graphite foldable phone hovering at a slight three-quarter angle, partly opened to a 110 degree hinge, screen glowing with an abstract cyan-and-magenta nebula wallpaper. Shoot it like a studio product photograph on a seamless dark charcoal backdrop with a soft top key light and a low rim light along the metallic hinge spine, picking out brushed aluminum micro-texture. Reflections on the inner OLED panel are subtle, no fingerprints. Left third of the canvas holds large white serif headline text reading "FOLD WHAT YOU CAN'T IMAGINE" with a smaller sans-serif tagline beneath: "Pre-order opens May 24". A slim rounded button labeled "Reserve now" sits in cyan. Right third is empty negative space with faint geometric grid lines for a tech feel. Color palette: graphite, soft cyan, hot magenta accent, off-white type. Mood is premium, calm, future-leaning. Final composition must read clearly even when cropped to 16:9 mobile.
