Build a bold vertical marketing hero for a sleep tracking app in the Format. Use the Color Palette across a calm, immersive night-themed background with a subtle glow and generous negative space. Place a clean crescent moon icon beside the Tagline near the upper third, using large, highly legible sans-serif typography with strong contrast. Below it, show a beautifully rendered mobile sleep app interface as the hero screenshot, with rounded cards, a sleep score visualization, soft data charts and a clear nighttime dashboard. Render every item in the App Screen Text exactly as written, with no extra labels or invented numbers. Keep the interface refined and easy to scan at mobile size, with consistent spacing, crisp edges and realistic app UI details. Use a centered composition, gentle depth, restrained shadows and a polished tech advertisement finish. Ensure all text is spelled correctly and remains fully inside the frame.
Use these details:
Tagline: "Sleep better tonight"
App Screen Text: ["Sleep score 87", "7h 42m asleep", "Deep sleep 2h 18m", "Bedtime 10:30 PM"]
Color Palette: "midnight navy, indigo, lavender and soft white"
Format: "9:16 vertical"
AI models never repeat themselves exactly, so your result will differ from the one here. Change the details to make it yours.
