Create a finished portrait birthday greeting card, 3:4 aspect ratio. Render only these exact words, with no other lettering: “HAPPY BIRTHDAY” as the large headline, “LOVE” directly beneath it as the second headline line, “To my favorite person” as a small supporting line, and “You make every day brighter.” as the final small message. Preserve the exact casing and punctuation. Set the words in flowing modern signature calligraphy with smooth, continuous pressure-curve strokes, broad organic swells, fine connecting hairlines, and generous capital entry swashes. Keep every word plainly legible. Use glossy saturated party-color lettering with crisp white outlines and small specular highlights; let the letter colors shift between coral-pink, tangerine, and turquoise. No flat untextured type. Build a centered stacked card layout: headline and “LOVE” occupy the central upper half; supporting lines sit beneath with clear separation; a small decorated birthday cake with a heart-shaped topper anchors the lower area as the scene’s hero prop. Keep generous safe margins and unobstructed text. Frame the composition with clustered multicolor balloons at the sides and dense but carefully placed confetti, bright sparkles, and short light streaks. Use a luminous, richly saturated candy gradient from hot pink through tangerine to turquoise, never pale or near-white. Bright party lighting, crisp highlights, subtle warm bokeh, high contrast, polished dimensional rendering. Keep the cake and decorations secondary to the exact headline. No people, devices, logos, or extra text.
