Premium Wireless Speaker on Stone Pedestal

[Format] Professional e-commerce product main image, square 1:1, dramatic dark tech-audio style. [Colors] Near-black background with a smoky brown haze #1a130c, warm gold rim light #c9973f pooling behind a stone pedestal, white headline type, black-and-gold bottom band, yellow subsidy numerals #f5c542, no frame border. [Layout] Giant headline across the top, a spec line beneath it, the cylindrical speaker centered on a rough rock plinth, a black banner strip spanning the bottom split between a subsidy figure and a discount note. [Subject] A matte black cylindrical wireless speaker with a subtly domed metal grille top, a thin brand wordmark on its face and a rubber base ring, lit by a single warm key light from behind. [Headline] Best-in-Class Sound Under $100 in huge white characters; the spec line reads 50-Hour Battery, IPX6 Waterproof, 15W Output; the bottom band shows Government Subsidy 15% in gold and Order Now for 15% Off or More with Limited Stock, First Come First Served in small type. [Badges] No separate claim pills; the spec line and subsidy figures carry all supporting claims. [Mood] Moody, powerful and premium, with cinematic backlighting that makes the black speaker feel heroic.
