A centered smartphone mockup dominates the frame as a hero visual for a meditation app, shown straight on with softly rounded edges and a clean, modern interface. Use the App Screen Content to shape the screen, with generous spacing, calm visual hierarchy and subtle glass-like interface details. Render the App Name prominently near the top of the phone and place the Tagline beneath it, keeping both lines perfectly legible and accurately spelled. Surround the device with a smooth, dimensional gradient using the Color Palette, with gentle light bloom behind the phone and a refined sense of depth. Keep the composition minimal and focused, with no distracting props, icons or extra text outside the phone interface. Use crisp app-presentation lighting, soft reflections on the device edges and a polished product-marketing finish. Deliver the composition in the Format.
