Present one mobile app icon alone, centered on a plain neutral background with a soft shadow. Use a standard iOS and Android rounded-square shape with a full-bleed background in the Primary Color and no inner border or frame. Place the Central Symbol exactly in the center, filling roughly 60 to 70 percent of the icon with even padding. Render it as one bold, simple letter with a confident silhouette and a subtle tonal gradient using the Secondary Color. Keep the letter highly legible at 48 pixels, with no thin strokes, tiny details or extra text. Use only the Primary Color, the Secondary Color and white if needed. Keep the finish matte, restrained and lightly dimensional rather than glossy or over-rendered. Use a clean square composition, crisp edges and balanced spacing. No additional symbols, logos, labels, watermarks or surrounding app icons.
Use these details:
Central Symbol: "A"
Primary Color: "matte black"
Secondary Color: "soft metallic gold"
