Create a finished, wide 16:9 kids’ birthday party banner. Use a bright, joyful party scene: a warm golden-to-peach background with soft colorful bokeh, small scattered confetti, and a few glossy balloon shapes near the edges. Keep the center bright and uncluttered so the message reads instantly. Add a small, beautifully decorated birthday cake with rainbow frosting in the lower-right corner as a clear party subject, separate from the lettering. Set only these exact words, with no extra text: “HAPPY” as a small centered eyebrow near the top; “Lily’s” as the huge central headline; “RAINBOW BIRTHDAY” directly below in a smaller but bold line; and “CAKE • CONFETTI • BIG WISHES” as a small centered finishing line near the bottom. Preserve the spelling, capitalization, and punctuation exactly. Use the same bold, rounded, extremely inflated balloon lettering throughout, scaled clearly by hierarchy. Every letter, including the small supporting lines, contains its own complete vertical ROYGBIV gradient: red at the top, then orange, yellow, green, blue, indigo, and violet at the bottom. Keep the colors intensely saturated, never pastel, and give the letters ultra-glossy candy lacquer, spherical convex faces, rounded terminals, and brilliant circular near-white highlights at each apex. Add a thin deep-plum edge and soft plum shadow for contrast without obscuring the rainbow fill. Arrange the text in a generous centered stack with even breathing room; make “Lily’s” the dominant focal point. Keep all lettering crisp, correctly formed, and easy to read at banner size. The cake has layered rainbow icing, cheerful sprinkles, and a few lit candles, with warm sunlight glinting on its frosting. Use soft golden party light and bright, colorful accents; avoid dark or muted areas. Keep confetti and balloons at the margins, never over the words. No logos, borders, extra lettering, or watermark.
