Create a finished wide horizontal party banner, 16:9. Render exactly this single text line, preserving capitals and spacing: “SO MUCH FUN”. The words occupy 82% of the banner width and 48% of its height, centered horizontally at y=27–75, with generous clear margins. Use huge bold rounded Rainbow Candy balloon lettering: expanded wide proportions, close-but-not-touching spacing, spherically convex pneumatic volume, hemisphere-rounded terminals, deep soft extrusion shadows. Every individual letter must contain its own complete vertical ROYGBIV gradient from red at its top through orange, yellow, green, blue and indigo to violet at its bottom; do not spread one gradient across the phrase and do not assign a single color per letter. Apply ultra-glossy candy lacquer, crisp circular near-white specular highlights at each letter apex, faint translucent reflected confetti, and a thin pale highlight rim. Stage the lettering against a bright saturated cyan-blue sky backdrop with a pale yellow sun flare from the upper right. Place large glossy rainbow balloons cropped at the far left and far right edges, behind the title; add warm white string-light bulbs in a shallow arc across the upper 14% of the frame. Scatter small crisp paper confetti rectangles and curled streamers in red, orange, yellow, green, blue, violet, plus soft golden bokeh dots around the outer edges only. Keep the central text face unobstructed and sharply legible from distance. High-key daylight, clean commercial banner rendering, ray-traced reflections, smooth ambient shadows, no dark areas, no extra words, no logos, no people.
