A vivid, high-energy birthday card, portrait. The background is a rich saturated gradient from hot pink at the top-left into tangerine orange at the bottom-right, with warm glowing bokeh circles and bright sparkle glints. A dense burst of multicolor confetti (turquoise, yellow, violet, white, coral rectangles, streamers and dots) fills the air and swirls around the lettering. Generous clusters of glossy balloons in turquoise, sunshine yellow, violet, red and white fill the left and right edges and the lower corners, with curling ribbons. Light streaks and star sparkles radiate softly. Center and upper-middle, the headline reads exactly "Happy 80th Birthday" in bold modern brush-script lettering, laid down with a loaded round brush: thick confident strokes with lively thick-to-thin modulation, slight dry-brush drag where strokes lift, letters connected in a fast free flow on a bouncing baseline, sizes varying. The word "80th" is the largest, about twice the height of the other words, as the focal point. Each word is a different punchy hue (sunshine yellow, turquoise, white, violet-magenta), every letter wrapped in a crisp thick white outline with a soft deep-pink drop shadow so it pops off the saturated background. The headline fills about 80% of the card width. Below the headline, the name "Grandma Rosa" in the same brush script, mid-size, in white with a thin violet outline and a gentle shadow, with a small hand-drawn brush flourish underline and a tiny cluster of sparkles. At the very bottom between the balloon clusters, a small line reading "With all our love" in a smaller casual brush script, white, clearly legible. Confetti never covers the letters. Bright, joyful, warm, celebratory, text perfectly legible, no extra words.
