Create a finished, print-ready birthday banner in a wide 3:2 landscape composition. Render exactly this wording, with no extra text: “HAPPY 6th BIRTHDAY KIARA”. Set it as the single dominant headline in three centered lines: “HAPPY” / “6th BIRTHDAY” / “KIARA”, keeping the spelling, capitalization, and ordinal exactly as supplied. Use heavy, firm geometric display lettering, near-square to slightly condensed proportions, even strokes, generous open counters, crisp joins, gently softened corners, and tight even spacing. The letters are smooth glossy coral-orange candy color with a clean bright highlight, thin crisp white keyline, and soft drop shadow; keep them structured and sharp, never inflated or balloon-shaped. Center the headline across the canvas, occupying roughly the middle 55% of its height, with ample clear contrast around every letter. Set the backdrop as a luminous, vivid hot-pink-to-turquoise party gradient, saturated rather than pale or near-white. Frame the title with generous clusters of glossy multicolor balloons at the far left and right edges, plus dense energetic bursts of bright confetti, curled streamers, tiny sparkles, and short light streaks. Keep decorations around the perimeter and out of the letter counters and headline area. Bright cheerful party lighting, crisp highlights, high color contrast, polished dimensional finish, clean readable banner composition. No additional lettering, logos, or devices.
