Present a modern smartphone mockup at a slight three-quarter angle, centered against a smooth luminous gradient built from the Color Palette. Show the App Screen Content clearly on the phone display with a calm, spacious interface, rounded controls, subtle depth, and generous negative space. Place the App Name prominently above or beside the device, followed by the Tagline in a clean, highly legible sans-serif typeface. Render both text elements exactly as written, with careful kerning and no spelling errors. Use soft studio lighting, a restrained phone shadow, faint violet reflections along the device edges, and a polished app-marketing composition. Keep the phone and typography dominant, with no extra logos, decorative objects, or unrequested copy. Frame the final artwork in the Format.
Use these details:
App Name: "Stillspace"

App Screen Content: "A 10-minute meditation timer with a breathing circle, session progress, and a Start Session button"
Color Palette: "deep violet, electric purple, lavender and white"
