Present one single mobile app icon for the App Type, centered on a square 1:1 canvas. Use a rounded-square iOS squircle with smooth corners, occupying about 70 percent of the canvas width, on a plain very light neutral background with a soft, subtle drop shadow beneath it. No device, hands, mockup, extra icons or text outside the icon.
Inside the icon, use the Color Palette to create a strong, high-contrast background and render the Icon Concept as one bold, centered symbol with generous padding. Follow the Icon Style with crisp geometric edges, a strong silhouette, restrained material texture and barely visible horizontal scanlines. Keep the design instantly readable at small sizes, using negative space intelligently and avoiding detailed scenes, thin lines, tiny details, glow, sparkles, lens flares, photographic texture and watermarks. Make the result feel like an original top-tier Dribbble or Behance app icon, not a copied logo or existing brand mark.
Use these details:
App Type: "Terminal app"
Icon Concept: "A command prompt chevron paired with an underscore cursor"
Icon Style: "Retro phosphor display with subtle horizontal scanlines"
Color Palette: "Phosphor green, near-black and soft gray"
