Create a high-converting ecommerce banner for a portable mini projector. Dark cinematic background with blue neon lights, modern and premium style. A small projector projecting a bright beam of light like a home theater. Add glowing effects, futuristic vibe, and depth. Include big bold text: "HOME CINEMA EXPERIENCE" and smaller text: "Turn your room into a movie theater in seconds". Add a "SALE -35%" label. Make it look professional, high quality, and realistic, like a big brand ad.
