Create a finished vertical birthday card, 3:4. Exact rendered text, preserve spelling and punctuation: small top line: “FOR THE BEST DAD” main headline, two lines: “HAPPY” / “BIRTHDAY, DAD” heartfelt message: “Thank you for being my steady hand, my biggest cheerleader, and home.” small footer: “WITH ALL MY LOVE · SEPTEMBER 10, 2026” Composition: a vivid saturated hot-pink upper field blending diagonally into turquoise and violet at the lower field, with a subtle tangerine center glow. The headline occupies the central 48% of the canvas. Render “HAPPY” and “BIRTHDAY, DAD” in bold contemporary connected brush script: loaded round-brush strokes, thick confident downstrokes, narrow rising strokes, slightly rough dry-brush drag at stroke exits, lively bouncing baseline and varied letter heights. Glossy saturated lettering: “HAPPY” tangerine-orange, “BIRTHDAY, DAD” turquoise and violet alternating by word; crisp thick white outline, white specular highlights, soft coral drop shadow. Make the lettering highly legible. Place the small top line in condensed uppercase white sans serif. Put the message below the headline in clean white rounded sans serif, centered over three short lines. Footer is tiny uppercase white sans serif at bottom center. A large matte ivory birthday cake with four glowing candles sits in the bottom-left foreground, partly below the message zone; piped frosting in pink, turquoise, and orange, one small gold heart topper. Generous clusters of glossy balloons frame both upper corners and the lower-right edge, in hot pink, turquoise, violet, tangerine, and yellow. Dense multicolor confetti burst, curled paper ribbons, bright sparkles and thin light streaks surround the type without covering it. Bright party lighting, warm candle glints, high color contrast, sharp print-card finish, no extra text, no watermark.
