Translate the App Type into the Icon Concept as one bold, instantly readable symbol centered inside a single iOS-style rounded-square app icon. Use the Icon Style with restrained 3D depth, gentle shading, soft highlights and believable rounded material, while keeping the siren silhouette simple and crisp. Use the Color Palette with strong contrast between the symbol and the icon background. Give the icon a subtle two-tone depth treatment without glow, lens flares or photographic texture. Present it as a real App Store or Google Play icon on a square 1:1 canvas, centered on a plain very light neutral background, occupying about 70 percent of the canvas width with a soft drop shadow beneath it. Use comfortable internal padding and clean negative space. Show no device, hands, mockup, extra objects, text outside the icon, variants, watermarks or detailed scene.
