Flagship Smartphone Flash Sale with 3-Year Warranty

[Format] Professional e-commerce product main image, square 1:1, high-contrast smartphone retail style with a clean grey stage, stacked red spec pills and a bold promo base. [Colors] Light neutral-grey background in the #e8eaec range with a soft floor reflection, primary accent vivid red (#e8283c) pills and bottom band, black product and dark slab badges, orange price disc; No frame border. [Layout] Two smartphones stand upright in the left half — one front-facing with a lit home screen, one angled behind showing its glossy back and dual camera; the right half is a stacked column of a big warranty headline, three red spec pills and a black coupon slab; a red banner runs along the bottom with an orange price circle overlapping its right end. [Subject] A slim black flagship-style smartphone with an edge-to-edge display showing a colourful app grid, clock widget reading "9:41" and weather widget; the rear view reveals a glossy black glass back with a vertical dual-camera bump and faint circuit-like light patterns; crisp studio reflections, no people. [Headline] Upper-right: "3-Year Warranty" in very heavy black caps. Beneath, three red rounded pills with white icon dots and text: "Ultra-Clear Camera", "Fingerprint Unlock", "256 GB Large Storage". A black slab reads "Join Membership — Click to Claim" beside a large "100 Coupon" in gold. Bottom red banner: "New Arrival, Slim Body" in white caps; orange disc: "Final Price $2999". [Mood] Confident, deal-forward and spec-loud; cool grey hardware polish heated up by red promo energy.
