Neonowy Mockup Dłoni Trzymającej Smartfon

Minimalist studio product photograph of a single human hand holding a modern edge-to-edge smartphone upright against a smooth lavender-to-pink gradient background. The forearm enters from the lower right corner, hand centered slightly to the left, fingers wrapping naturally around the dark bezel with the thumb on the right side. Dramatic dual neon gel lighting casts cool cyan-blue highlights along the left edge and deep magenta-purple tones in the shadows on the right. The sleek phone features rounded corners and a centered pill cutout at the top. Displayed on the screen is a clean monochrome design-tech landing page with an abstract black logo top-left, a small rounded "Menu" button top-right, two wide pale rectangular wireframe cards, and centered onboarding typography below. The main headline reads "[Welcome to the future of design with Terot]", followed by smaller gray subtext "[Create intelligent design systems and AI-powered visual experiences.]", an outlined pill button labeled "[Create account]", and a text link "[Login]". Cinematic tech-advertising aesthetic, realistic skin texture, soft screen glow, and generous negative space.
