Create a finished horizontal party banner, 16:9. Render all text exactly as written and keep every line clean, correctly spelled, and highly legible. Top centred small eyebrow: “LET’S CELEBRATE”, in compact white rounded uppercase lettering with a thin violet outline. Main headline across the central 64% of the canvas on two centred lines: “SO MUCH” / “FUN”. Make the letters extra-wide, bold rounded display forms with extreme pneumatic 3D inflation, spherical convex volume, hemisphere terminals, ultra-glossy candy lacquer, and large circular near-white highlights. Each individual letter must contain its own complete vertical ROYGBIV gradient: red at its top, orange upper area, yellow through green at centre, blue and indigo lower area, violet at the bottom. Do not spread one gradient across the phrase; every single letter is a full rainbow. Add a crisp white edge and soft violet-blue drop shadow for separation. Below the headline, centred: “LAUGHS • GAMES • TREATS” in deep violet rounded uppercase lettering on a slim white ribbon with rounded ends. Scene: bright sky-blue to pale-aqua backdrop, high-key daylight from upper right, warm golden bokeh string lights, glossy helium balloons cropped along the left and right edges, scattered paper confetti in red, orange, yellow, green, blue and violet. Add subtle white starbursts and tiny translucent bubble spheres around the title. Keep a generous clean central reading area; no dark areas, no muted colours, no extra text, no logos. High-resolution commercial party-banner render, ray-traced reflections, sharp typography, vivid full-chroma colour.
