Smart Band Product Hero Image

[Format] Professional e-commerce product main image, square 1:1, clean tech-gadget style with an aqua-teal gradient field and a single floating hero device. [Colors] Background is a smooth aqua-to-mint gradient (#7fe3d4 to #bff2e8) with soft abstract ribbons and dots. Accents are white type blocks, teal-green numerals on the device screen, and a dark teal bottom bar. No frame border. [Layout] A white brand strip with a thin teal border runs across the very top. Below it, a white rounded panel holds a small eyebrow line and a two-line headline. The smart band floats centre-right at a dynamic angle. The bottom quarter is split into teal blocks with price and service text. [Subject] Centre-right: a sleek black smart band with a slim curved strap, a polished silver hinge clasp, and a round touch display glowing with teal graphics - a dotted activity ring, footsteps icon, a large "10,000" step counter and a "100%" ring gauge. Gentle drop shadow, crisp studio rendering. No people. [Headline] Inside the white panel: a small teal centred line "Ultra-long 20-day battery life", then two heavy dark-teal display lines: "50m water resistant" and "Large touch display". [Badges] Bottom-left teal block: small white caps "Your price" above a huge white "$169" with a currency mark. To its right, a dark teal bar reads "Express courier, same-day delivery available" above a white strip with teal bold "Heart-rate tracking, mobile payments". The top strip reads "YOUR LOGO | Official flagship store". [Mood] Fresh, sporty and dependable; cool aqua lightness around one precise teal-lit device with clear utility claims.
