Create an ultra-wide horizontal celebration banner, 21:9. Render the exact headline “SO MUCH FUN” centered across the canvas in three stacked-but-tight words: “SO” small at upper center, “MUCH” dominant across the middle, “FUN” large at lower center. The headline occupies 78% of the banner width and remains fully inside generous safe margins. Custom bold rounded display lettering with extreme spherically convex balloon inflation, thick soft contours, rounded hemisphere terminals, ultra-glossy transparent candy-lacquer surface, subtle inner depth, and a crisp circular near-white specular highlight at the apex of every glyph. EACH INDIVIDUAL LETTER contains its own complete vertical ROYGBIV gradient: saturated red at top, orange beneath, yellow through the center, green, blue-indigo, and violet at bottom; never one solid color per letter and never one gradient stretched across the phrase. Stage it against a bright cyan-blue outdoor party sky with a soft white sun flare from upper right. Scatter small floating confetti pieces in red, orange, yellow, green, blue, and violet around the outer edges only; keep the text unobstructed. Out-of-focus warm string-light bokeh runs along the far top edge. Add cropped glossy rainbow balloons at the extreme left and right edges as framing, never competing with the words. Strong warm sunlight creates clean brilliant highlights and soft grounded shadows beneath the inflated letters. Clean high-key commercial banner art, ray-traced glossy reflections, sharp readable typography, high saturation. No extra words, no logos, no dark background, no muted colors, no flat or matte lettering.
