Create a vibrant sticker with the bold text Purely Madness emblazoned across it, set against a deep black background that absorbs all light, with the text itself in a bright, eye-catching color such as neon green or electric blue, in a stylized, graffiti-inspired font with sharp lines and angular edges, where the words Purely and Madness are stacked on top of each other in a slightly overlapping manner, giving the sticker a dynamic and chaotic feel, with a subtle gradient effect to give the text a sense of depth and dimensionality.
