Bluetooth Dual-Mode Mechanical Keyboard - Cool Glossy Promo

[Format] Professional e-commerce product main image, square 1:1, cool glossy tech-accessory promo with a rounded glassy frame. [Colors] Icy blue gradient background (#dfeefa) enclosed by a translucent blue frame with a wavy top banner; royal-blue title; white hardware; purple price block. No plain border - the blue glass frame is part of the design. [Layout] The wavy blue ribbon across the top carries a logo pill; the title spans the upper area; the keyboard lies flat across the middle on a pale desk plane; a purple price block sits bottom-left with a blue claim bar running along the bottom. [Subject] No people. A slim white low-profile mechanical keyboard with rounded keycaps, shot at a low three-quarter angle floating just above a pale reflective desk, lit with soft blue ambient light and faint glassy highlights. [Headline] Centered royal-blue display type: "Bluetooth Dual-Mode Mechanical Keyboard"; beneath it a smaller blue line with thin separators: "Comfortable & durable | Low-noise keys | Wireless connection". [Badges] Top ribbon pill: "YOUR LOGO"; bottom-left purple block: "Yours for $199" with $199 oversized; bottom blue bar in white caps: "Free mouse pad with every purchase". [Mood] Clean, cool and gadget-forward; icy blue glassiness with crisp white hardware and tidy promo blocks.
