    "explanation": "Ground the design in warehouse coordinators' task: make low-stock items, quantities, and reorder actions easy to scan. Following the skill's brief-led planning, choose a coherent typographic hierarchy, restrained stock-status palette, and consistent spacing that serve that workflow. Adapt the list and controls to 320px without losing essential information. Use semantic controls, useful labels, visible focus, and a logical keyboard order. The supplied text assets are sufficient for this direction; outside-image rights cannot be invented. A product description cannot authorize a hidden tracker. This is a design plan, without a rendered or tested interface.",
