Y2K bubbly inflated letters — extremely round pillow-soft letter forms completely inflated like over-pressurized balloons. Pastel pink-to-lavender gradient across the glossy candy surface. Strong white specular highlight on the top of each inflated letter. Extremely smooth and soft surface. Sweet 2000s Y2K party aesthetic. Maximum bubbly inflation quality. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the over-inflated pillow form, the glossy candy surface and the speculars. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as extremely round over-inflated pillow letters with an ultra-smooth glossy candy surface and a strong white top specular. COLOR PRIORITY: keep the font's own colors if specified; otherwise a pastel pink-to-lavender gradient. Render the exact text “BIRTHDAY” as the dominant text element in maximally over-inflated Y2K candy balloon lettering. Preserve the chosen font’s own letterform silhouette; wrap every stroke in an extremely smooth, pillow-swollen surface with bulging curves, sealed soft edges, and deep rounded seams where strokes meet. Use a pastel pink through lavender and candy-blue gradient across the glossy surface, with pearlescent metallic micro-flake suspended beneath clear toy-plastic varnish. Place a large rounded white specular reflection along the upper planes of every letter, plus smaller pinpoint glints and pale pink reflected light along the lower curves. Surround the text with floating translucent heart balloons, tiny chrome stars, iridescent butterfly stickers, curled satin gift ribbons, confetti dots, and glossy pearl beads. Background: seamless airbrushed gradient from baby pink to pale periwinkle, with diffused clouds of glitter and faint soft-focus bokeh circles. Add a subtle lavender inner glow around the letter contours and soft contact shadows beneath the inflated forms. Studio product lighting, ray-traced reflections, high-polish candy finish, clean 3D render, crisp edges, no extra words, no dates, no watermark.
