Show two versions of the same mobile app icon side by side, one in light mode and one in dark mode. Each icon is a standard full-bleed rounded square with no inner border or frame. Use the Central Letter as the only mark, centered and filling roughly 60 to 70 percent of each icon with an even margin. Set the light-mode icon to the Primary Color and the dark-mode icon to the Secondary Color, using a simple high-contrast treatment for the letter that remains identical in both versions. Keep the letter bold, geometric and clearly legible at 48 pixels, with no extra text, symbols or tiny details. Use flat color with only a very subtle tonal transition if needed. Place both icons on a clean neutral background with a soft shadow beneath each, aligned at the same size and height. No real logos, watermarks or placeholder app labels.
Use these details:
Central Letter: "A"
Primary Color: "soft lavender"
Secondary Color: "deep violet"

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