实验性排版海报

A bold, experimental typographic poster featuring the large centered word '{argument name="text" default="design"}' in lowercase, ultra-heavy geometric sans-serif font with thick slab-like strokes and perfectly rounded edges, reminiscent of modern brutalist. The same letters are being shown blurry under the main letters and duplicated many times going down with a blur effect. {argument name="background colors" default="Blue and purple soft gradient"} background.
