Create an ultra-wide 21:9 outdoor celebration banner with a clean, print-ready graphic composition. Exact readable text, set precisely: Primary headline, enormous across the center in two stacked lines: “SO MUCH” / “FUN” Small supporting line above: “LET THE GOOD TIMES ROLL” Small supporting line below: “A DAY MADE FOR SMILES” The headline occupies 72% of the banner width and 54% of its height. Design custom bold rounded display lettering with very wide tracking, extreme spherical pneumatic inflation, deeply rounded hemisphere terminals, ultra-glossy candy-lacquer skin, and crisp circular near-white specular highlights at the top-right apex of every letter. Every single letter independently contains a complete vertical ROYGBIV gradient inside its own shape: red top edge, orange upper zone, yellow and green through the center, blue and indigo below, violet at the bottom. Do not assign one hue per letter; do not run one rainbow across the whole word. Maintain full chroma and sharp legibility with a thin clean white keyline and a soft colored contact shadow beneath each inflated character. Set the small lines in compact white uppercase rounded sans-serif, centered, with generous clear space. Background: bright cyan-blue sky gradient, soft warm sunlight from upper right, pale cream cloud puffs at far edges, multicolored paper confetti scattered around the headline, glossy rainbow balloons cropped at the left and right edges, and a subtle row of tiny warm-white string lights along the top border. Keep all decorations outside the headline’s reading area. High-resolution commercial event-banner rendering, ray-traced glossy reflections, crisp vector-like typography, no dark areas, no extra words, no misspelled text.
