A minimalist digital banner graphic rendered in a vibrant purple gradient. The composition features a central, slightly darker horizontal rectangular panel that houses clean, white sans-serif typography. The main text reads 'BANNER DE PRUEBA', with a secondary label below it reading 'HOME · MEDIO'. The background is decorated with a pattern of white outline circles of varying sizes distributed symmetrically across the frame, adding a sense of depth and playful geometric texture. The lighting is uniform and flat, characteristic of a vector or digital graphic design, emphasizing the sharp contrast between the white elements and the deep purple backdrop. The overall aesthetic is professional, modern, and suitable for web header or UI design purposes.
