Create a finished 16:9 horizontal birthday banner. Render only these exact words, with this casing and no additional text: small top line “Happy”; dominant center headline “ONEderful”; supporting line “birthday to me”. Set “ONEderful” in large, firm, near-square geometric display lettering with even heavy strokes, open counters, crisp joins, and gently softened corners; keep the letters structured, not rounded, inflated, or balloon-shaped. Give the headline a smooth glossy coral finish, one crisp highlight, a thin white keyline, and a soft short drop shadow. Set the other two lines in smaller, clean bold display lettering with the same coral finish and white keyline. Use a bright, saturated turquoise-to-violet party gradient background, with strong contrast behind the words. Place “Happy” centered in the upper 15%, “ONEderful” across the central 40%, and “birthday to me” centered beneath it. Add a small frosted birthday cake at the lower center with a single lit numeral-one candle, clearly separate from the lettering. Frame the text with generous clusters of glossy multicolor balloons at the far left and right edges, and energetic confetti bursts radiating from both upper corners; add a few bright sparkles and short light streaks. Keep every word unobstructed and legible. Use bright, even party lighting, crisp edges, saturated color, and dimensional highlights. No pale or near-white background, no dark stage, no extra words, no devices.
