Design one professionally made App Store or Google Play listing screenshot in the Format. Use a solid background based on the Brand Color, with a restrained near-black foundation and clear contrast. Place the Headline at the top in large, bold, clean sans serif type, on no more than two lines, rendered exactly as written. Add the Subline beneath it with smaller, highly legible typography.
Place a generic modern smartphone as the main element below the text, shown at the Device Angle with thin bezels, no brand logo, and a soft realistic shadow. Set the app identity in the phone interface to App Name. Show the Screen Content inside a believable crypto wallet UI with a 9:41 status bar, readable portfolio rows, sensible values, clean spacing, and the Brand Color used consistently for accents and controls. If App Screenshots are available, place them inside the phone screen exactly as supplied without redrawing. If an App Icon is available, use it exactly within the interface.
Keep generous margins around every element. Use crisp typography, realistic phone rendering, sharp screen content, and accurate spelling. Avoid star ratings, reviews, award badges, store badges, download counts, logos, watermarks, decorative glow, lens flares, sparkles, glassmorphism, and busy backgrounds.
