A single mobile app icon centered alone on a plain white background, with a standard rounded-square silhouette and a full-bleed background in the Primary Color. Place the Central Symbol in the center, filling roughly 60 to 70 percent of the icon with even padding. Render it in the Secondary Color using bold, simple shapes and a confident silhouette that remains immediately readable at 48 pixels. Keep the design flat, calm and minimal, with no thin lines, tiny details, border, inner frame or extra text. Use no more than the Primary Color, Secondary Color and white. Add a soft, subtle shadow beneath the icon for gentle separation from the background. Show one icon only, front-facing and square, with clean edges and balanced spacing. Do not include other symbols, brand logos, trademarked characters or watermarks.
Use these details:
Central Symbol: "a simple crescent moon with one small star cutout"
Primary Color: "midnight blue"
Secondary Color: "soft pale gold"
