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. Square composition. Render the exact text “birthday gir” as the sole hero lettering, centered in two compact lines: “birthday” above “gir,” preserving every character exactly. Make each letter feel maximally inflated, like an over-pressurized candy balloon, with extremely round pillow-soft surfaces and bulging edges that seem almost ready to pop. Coat the letters in a glossy pastel pink-to-lavender gradient, with subtle candy-blue iridescence along the lower curves. Place a bold, rounded white specular highlight across the top of each inflated letter; add soft matching inner glow and gentle contact shadows so the forms feel plush, dimensional, and toy-like. Keep the text large and immediately legible, with lively spacing and no added wording. Use a smooth pale pink and lavender background, brighter behind the lettering and softly shaded toward the edges. Surround the words with a few small glossy hearts, starbursts, and tiny party-sparkle accents, leaving generous clear space around the text. Sweet, playful Y2K birthday-party energy; polished candy surfaces, soft glow, and buoyant visual rhythm.
