Lumen E-Reader Paperlight

Clean product photo of a slim sage-green e-reader called 'Lumen Paperlight', screen showing crisp black text on a warm paper-white page, held upright in an invisible mount. Shot against a soft cream seamless background with a gentle vignette. Diffused overhead light, warm front glow simulating the reader's adjustable frontlight, matte bezel with a subtle soft-touch texture. Calm, bookish tech-ad mood, 4:5 vertical, centered, delicate shadow. Tagline space above: 'A whole library, one page at a time.'
