Create a premium commercial product image for an original unbranded folding e-ink reading lamp. The lamp has a thin warm adjustable LED bar, a subtle e-ink control strip, matte anodized-aluminum double hinges, and a recycled-fabric carrying sleeve. Show exactly one lamp fully open at a practical reading angle, with the sleeve beside it and one open book without visible text for scale. Use a landscape 4:3 clean three-quarter composition on a low travertine plinth against a graphite-to-warm-gray studio gradient. Controlled softbox light defines precise cool edges while the lamp creates a warm pool across the pages. Emphasize brushed metal, frosted diffuser, fine hinge mechanics, woven fabric, and realistic shadows. No readable interface text, logos, watermark, floating parts, duplicated lamp, impossible reflections, broken hinges, or visible cable clutter.
