Build one mobile app icon around the Central Symbol. Use the Primary Color as the full-bleed background and the Secondary Color for the symbol, with white allowed only as a small supporting highlight if needed. Keep the Central Symbol centered and scaled to fill roughly 60 to 70 percent of the rounded-square canvas, with even padding and a silhouette that remains instantly readable at 48 pixels. Use bold, simple geometry and a flat illustration style with clean edges, no thin lines, tiny details, text, border or inner frame. Present the icon alone, centered on a plain neutral background with a soft, subtle shadow beneath it. Keep the design calm, friendly and suitable for a budgeting app. Use no real logos, trademarked characters or watermark.
Use these details:
Central Symbol: "simple wallet silhouette"
Primary Color: "deep teal"
Secondary Color: "warm white"

Your result will come out close to the example rather than identical to it. Change the details to make it yours.
