Luksusowy laptop Concierge

Create a photorealistic luxury website mockup displayed on an open dark space-gray MacBook Pro, floating horizontally and supported from below by a single elegant hand against a plain soft light-gray studio background. The laptop is angled slightly in perspective, screen facing the viewer, thin black bezel with a small top notch, visible keyboard base edge and ports, premium minimal product-photography lighting with subtle shadows. On the screen show a full-width French luxury concierge landing page for {argument name="brand name" default="Maison Lumière"}: a hero photo of the Eiffel Tower viewed through a large stone archway, muted Paris skyline and greenery below, refined editorial typography. Website header: brand name at top left, and exactly 4 small uppercase navigation links at top right: “À PROPOS”, “SERVICES”, “TÉMOIGNAGES”, “CONTACT”. Centered hero copy: small line “— MAISON LUMIÈRE · PARIS —”, oversized elegant serif headline “{argument name="headline text" default="Votre temps est précieux. Nous nous occupons du reste."}”, smaller subtitle “{argument name="subtitle text" default="Conciergerie privée haut de gamme à Paris"}”, and a thin outlined button reading “{argument name="button text" default="DÉCOUVRIR NOS SERVICES"}”. Use a sophisticated beige, ivory, charcoal, and soft blue color palette, high-end fashion/luxury aesthetic, realistic reflections on the laptop glass, crisp screen details, shallow depth of field, no extra objects, no watermark.
