Ikona Aplikacji ze Świecącą Cyfrą Gradientową

A polished mobile app icon featuring a single large stylized numeral [9] centered slightly to the left on a square canvas with smooth rounded corners (iOS-style app icon squircle). The numeral is a thick, smooth, glossy 3D glyph rendered with a vivid gradient transitioning from golden yellow and orange at the top-left, through hot pink in the center, to rich violet and electric purple at the lower curve. A soft neon rim light and inner glow surround the digit, featuring a bright warm glow on the upper-left edge and a deep magenta-purple glow along the bottom. The right side of the numeral dissolves into a dynamic particle burst of circular dots and fine speckles in matching warm-to-cool hues scattering outward to the right. Deep midnight navy-to-purple background with subtle radial shading and a faint vignette. Clean, iconic composition, high contrast, crisp edges, vibrant lighting, no additional text, no borders, no watermarks.
