Build one mobile app icon around the Central Symbol. Use the Primary Color as the full-bleed background and the Secondary Color for the central form, with white reserved for restrained highlights. Give the icon a soft 3D finish with gently rounded edges, subtle dimensional shading and diffuse light, avoiding gloss or complex surface detail. Keep the Central Symbol centered with even padding and sized to fill roughly 60 to 70 percent of the rounded-square canvas, so its silhouette remains immediately readable at 48 pixels. Use bold, simple shapes and one clear idea only. Show the icon alone on a plain neutral background with a soft grounded shadow. Include no border, inner frame, extra symbols, text, logos or watermark. Render a clean, friendly social app icon in a square format.
Use these details:
Central Symbol: "friendly ghost mascot"
Primary Color: "lavender"
Secondary Color: "soft white"
