Create a finished square Instagram birthday post, 1:1, with all text rendered exactly as quoted. Centered typographic composition with no people, no devices, no logos. TEXT HIERARCHY: Main headline in four centered lines: “HAPPY” / “5TH” / “BIRTHDAY” / “SHAARVI”. Set all four lines in custom bold modern brush-script lettering, not a font-library look: connected hand-lettered strokes made by a loaded round brush, thick confident downstrokes and narrow upstrokes, slightly rough dry-brush drag where each stroke lifts, energetic bouncing baseline and varied character height. “HAPPY” is tangerine-orange, “BIRTHDAY” is saturated turquoise, “SHAARVI” is violet-to-hot-pink with tiny glossy highlight strokes; every headline word has a thick crisp white contour plus a tight deep-violet drop shadow for sharp separation. Make “SHAARVI” 15% larger than the other lines, with an extended final flourish curling beneath it. Set “5TH” in saturated turquoise brush-script lettering, matching the headline style and separation. Small support lines are clean, compact uppercase white lettering with wide tracking. Background: vivid saturated candy-color radial gradient, hot pink at upper left flowing into tangerine at center and turquoise/violet at lower right; bright, never pale, never grey, no dark stage. Frame the text without obscuring it: dense suspended confetti in cobalt, lemon yellow, coral, turquoise, violet, and white; glossy balloon clusters at top left and top right, plus smaller balloons along the lower side edges. Add pinpoint sparkles, warm circular bokeh, and thin diagonal light streaks behind the lettering. Use crisp high-contrast party light, white glints on balloon curves, soft colored bounce light around the lettering, clean central negative space, polished social-post finish. Keep every word fully legible and accurately spelled.
