Render as inflated 3D bubble letters in graffiti street art style. Bold outline strokes visible around each letter — thick black or dark outline like spray paint marker work. Colors: vibrant urban palette — electric yellow, hot orange, acid green, royal blue — layered and saturated, not pastel. Background: subtle concrete wall or brick texture, desaturated so letters pop. Letters feel massive and commanding, filling the frame. Energy: street credibility, spray can culture, skate park aesthetic. Glossy surface but with edge — not cute, bold. Square 1:1. Bubble Letters Graffiti text centered. Atmospheric background matching the style.
